Vă rugăm să rețineți, aceste informații se bazează pe cele mai bune cunoștințe ale noastre la momentul postării și sunt supuse schimbării pe măsură ce ancheta noastră continuă. Un raport final de incident cu acţiuni preventive va fi postat după finalizarea investigaţiei noastre. Dacă ați avut un impact în afara celor enumerate mai jos, vă rugăm să accesați Google Cloud Support folosind [**https\://cloud.google.com/support**](https://cloud.google.com/support). ## Data/ora emisiunii Incident Start:19 octombrie 2026 23:00 US/Pacific / 20 octombrie 2026 07:00 BST Sfârşitul incidentului: 20 octombrie 2026 05:10 US/Pacific / 20 octombrie 2026 13:10 BST Durata: 6 ore, 10 minute ## Rezumat Luni, 19 octombrie 2026 (marți, 20 octombrie BST), mai multe servicii Google Cloud Platform în regiunea Europa-Vest2 au suferit întreruperi ale serviciilor, rate ridicate de eroare, termene de programare a aplicațiilor (API) și latență de procesare pentru o perioadă de 6 ore și 10 minute. Perturbarea a fost declanșată de o întrerupere a energiei electrice la centrul de date care găzduiește zona de disponibilitate Europa-west2-b, care a luat temporar servere gazdă fizică, hardware de rutare a rețelei și sisteme de stocare offline. Acest lucru a cauzat ulterior întârzieri secundare în ceea ce privește infrastructura regională fără impact. ## Preliminary Root Cause Incidentul a fost declanşat când a avut loc o întrerupere a reţelei electrice la centrul de date care găzduia zona de disponibilitate Europa-west2-b. Pentru a menține puterea continuă în timpul întreruperii, transferul automat la sistemele de alimentare de rezervă a instalației a fost declanșat imediat. Încărcătura instalației a fost transferată la bateriile de alimentare cu energie electrică (UPS) fără întrerupere în timpul secvenței de pornire a generatoarelor diesel de urgență la fața locului. Sistemul de automatizare Logic Controller programabil (PLC) (atât PLC primar cât şi de rezervă) nu a iniţiat operaţiunile logice de pornire/transfer automat ale generatoarelor, împiedicând generatoarele de rezervă să-şi asume sarcina. Atunci când rezervele de baterii UPS au fost epuizate, servere de gazda fizica, tesatura de comutare a retelei, si retele de stocare locale dedicate Europei-Vest2-B a pierdut puterea si a plecat offline. Secvența evenimentelor care au condus la impactul asupra clienților a fost următoarea: * La 22:53 US/Pacific (20 octombrie, 06:53 BST), o întrerupere a energiei electrice a avut loc la unitatea de datecenter care găzduiește zona de disponibilitate europe-west2-b, precum și o eroare PLC (Programable Logic Controller) pornire a împiedicat generatoarele de urgență ale instalației să-și asume sarcina electrică. Încărcătura instalației a continuat să fie susținută de băncile de baterii UPS până la epuizarea bateriilor, începând cu ora 23:00, SUA/Pacific (20 octombrie, 07:00 BST). * Atunci când serverele gazdă fizice, infrastructura de stocare locală și hardware-ul de agregare a rețelei în Europa-west2-b au pierdut puterea, au cauzat cazuri, replici de baze de date și noduri de muncă în acea zonă să devină imediat inaccesibile. * Mecanismele regionale de direcţionare a traficului şi aplicaţiile clienţilor au iniţiat o esecare automată către infrastructura disponibilă în zonele de disponibilitate adiacente din regiune. * Cross-zona de proceduri de la distanță apeluri de la avioane regionale de control serviciu direcţionate către metadate şi componente de catalog în zona offline intalnit timeouts, cauzand standuri de depunere de locuri de muncă iniţiale şi API latency Spikes. * Afluxul brusc de execuții de interogare redirecționate, eșecuri de baze de date de înaltă disponibilitate, și volum de muncă calculat saturate sloturi disponibile și capacitate de procesare în alte zone de disponibilitate, crearea de cozi de admisie ridicate, failover de baze de date întârziate, și intermitente 500 și 503 erori API în întreaga regiune. Inginerii Google au început o analiză completă a cauzelor profunde (RCA) și vor furniza informații suplimentare după ce sunt disponibile. ## Remediation Inginerii Google au fost alertați cu privire la perturbarea prin sisteme automatizate de monitorizare și sonde la ora 23:08 US/Pacific la 19 octombrie (20 octombrie 07:08 BST), care au detectat rate ridicate de eroare API, termene de depunere a unui loc de muncă și pierderea accesibilității infrastructurii în Europa-Vest2-b. Echipele de ingineri s-au mobilizat imediat pentru a izola infrastructura afectată și a începe recuperarea: * ** Izolarea traficului:** Inginerii Google au izolat zona de disponibilitate offline (europe-west2-b) prin ajustarea rutei serviciilor regionale în afara infrastructurii afectate, prevenind cererile clientilor cross-zone de la sincronizarea cu obiectivele offline. * ** Reprioritizarea sarcinilor și protecția resurselor:** Inginerii au ajustat alocările programatorilor și limitele de capacitate în cadrul infrastructurii neimpactate pentru a prioritiza rezervările active ale clienților, pentru a reduce disputa de resurse privind sloturile de execuție și pentru a scuti întârzierile în coadă pentru volumul de muncă regional. * ** Restaurarea grilei de putere:** Inginerii instalaţiei de la faţa locului au efectuat o restaurare graţioasă a unei alimentaţii de utilităţi stabile odată ce alimentarea cu utilităţi a revenit, într-o oră. Ca urmare, ei s-au concentrat și au finalizat o resetare și au testat controlerele de automatizare a generatorului de rezervă de urgență pentru a restabili puterea instalației. * ** Reactivarea infrastructurii agresive:** Inginerii Google au repornit sistematic nucleul infrastructurii și serviciilor Google Cloud. * ** Readmission Controlled Traffic:** Odată ce sănătatea sistemului și integritatea de stocare au fost verificate, inginerii au executat treptat, re-admiterea controlată a traficului înapoi în zona Europa-Vest2-b, permițând backlog-uri de locuri de muncă acumulate pentru a șterge fără probleme. Până la 05:10 US/Pacific marți, 20 octombrie (13:10 BST), disponibilitatea serviciilor a fost recuperată pentru marea majoritate a volumului de muncă al clienților, iar rezoluția pentru majoritatea clienților din cadrul serviciilor Google Cloud Platform din regiune a fost confirmată. Ca urmare a recuperării unei mici cozi de muncă izolată rămasă, notificarea de închidere pentru incident a fost postată de 07:03 US/Pacific (15:03 BST). ## Descriere de impact Între luni, 19 octombrie 2026, 23:00 US/Pacific (marţi, 20 octombrie 2026, 07:00 BST) şi marţi, 20 octombrie 2026, 05:10 US/Pacific (13:10 BST), clienţii care utilizează servicii Google Cloud Platform în regiunea Europa-Vest2 au suferit întreruperi ale serviciilor în două faze consecutive, pe o durată totală de 6 ore, 10 minute. În faza inițială de la 23:00 la 04:29 US/Pacific (07:00 la 12:29 BST) (durata 5 ore, 29 minute), clienții au experimentat rate de eroare ridicate, API timeouts, și întârzieri de procesare până la majoritatea serviciilor Google Cloud Platform recuperat. Ca urmare a restaurării serviciilor de platformă, unele lucrări de lucru ale clienților care rulează în situații de calcul motor au avut o coadă de recuperare mai lungă. Prin 04:46 US/Pacific (12:46 BST) noua creatie de masini virtuale a fost reluata si pana la 05:10 US/Pacific (13:10 BST) peste 99% din masinile virtuale ale motorului de calcul erau intr-o stare sanatoasa. Orice clienți rămași care se confruntau probleme Virtual Machine au fost direcționate pentru a depune o problemă de suport pentru clienți ca pe procedura normală. În timp ce pană fizică de energie a fost izolată strict de instalațiile de datecentric din Europa-Vest2-b, unii clienți care desfășoară activități de muncă în zone neafectate (europe-west2-a și europe-west2-c) sau de-a lungul arhitecturilor regionale au avut, de asemenea, un impact neașteptat. Cauzele principale au fost 1\) creșterea instantanee a cererii asupra capacității de calcul neimpactate și 2\) dependențe sincrone de validare a planului de control-plane între limitele interzonale. Produse afectate incluse: BigQuery, Looker, Google Compute Engine, Google Kubernetes Engine, Regional Persistent Disk, și Cloud SQL. Aceste servicii s-au confruntat cu probleme neașteptate de degradare și eșuare determinate de epuizarea bruscă a capacității de calcul din cauza creșterii cererii și a întârzierilor API-plane de control care așteaptă validarea din zona offline. Încărcăturile și resursele găzduite în întregime în Europa-Vest2-b au devenit inaccesibile. Serviciile de stocare a datelor cu capacitate de eșuare, cum ar fi Cloud SQL, AliadDB, Memorystore for Redis și Cloud Bigtable au eșuat în zonele neafectate din apropiere în timpul întreruperii Europa-Vest2-b. Serviciile multizonale și regionale care se întindeau în întreaga regiune Europa-Vest2 au înregistrat erori de latență, de API tranzitorii (cum ar fi erorile HTTP 500 și 503) și de admisie a sarcinilor, care au stat la baza unui blocaj de trafic concentrat asupra resurselor regionale neafectate și a unor apeluri la zone încrucișate la componente offline temporizate. Operațiunile de scriere a depozitelor din regiune au cunoscut o rată de eroare tranzitorie în timpul perioadei inițiale de eșec, iar cozile regionale de admisie a interogărilor au atins un vârf temporar înainte de a se subsidia rapid ca capacitate reechilibrată. Următoarele servicii Google Cloud Platform au avut impact: * ALYDB for PostgreSQL * Apigee * BigQuery Data Transfer Service * Cloud Data Fusion * Cloud Filestore * Cloud Firestore * Cloud Load Balance * Cloud Memorystore * Cloud NAT * Cloud Run * Cloud Spanner * Statii de lucru Cloud * Datastream * Dialogflow CX * Motor Google App * Google BigQuery * Google Cloud Bigtable * Fluxul de date Google Cloud * Google Cloud Dataproc * Google Cloud NetApp Volumes * Google Cloud Pub/Sub * Google Cloud SQL * Google Cloud Storage (GCS) * Motor de calcul Google (GCE) * Motor Google Kubernetes (GKE) * Google SecOps (Security Information and Event Management \[SIEM\] and Security Orchestration, Automation, and Response \[SOAR\]) * Looker (Google Cloud core) * Looker Studio * Managementul fluxului de aer (Google Cloud Compuser) * Managed Service for Apache Kafka * Memorystore for Memcached * Memorystore for Redis * Memorystore for Redis Cluster * Memorystore for Valkey * Network Connectivity Center * Disc persistent * Private Service Connect * Discurs-la-Text * Virtual Private Cloud (VPC) * Motor VMWare

      ## Incident Report ### **Summary** On Monday, 19 Oct 2026 (Tuesday, 20 Oct BST), a data center facility that hosts europe-west2-b, experienced an external electrical power disruption. This resulted in service unavailability for workloads located in this zone. As traffic was redirected to alternative cloud regions or unaffected zones within europe-west2 cloud region, these workloads experienced transient latency and elevated errors affecting services across europe-west2.  The primary impact was mitigated after 6 hours 8 minutes. ### **Root Cause** **Facility architecture and background:** The data center facility in the UK region hosts Cloud clusters serving the europe-west2-b zone, which form part of the multi-zonal europe-west2 Cloud region. The site relies on a 2N utility power architecture—meaning the facility has complete duplicate power paths for every critical load—backed by a central high-voltage generator bank managed by a dual-redundant Programmable Logic Controller (PLC). Primary utility power is supplied to the facility via two independent feeders (A and B), supplemented by a standby utility connection configured for manual campus-wide transfer during maintenance operations or emergency events. The two high-voltage primary feeders terminate at separate primary intake switchboards capable of closed-loop operation if either board is taken offline. Switching between the primary and standby utility providers utilizes open transitions and key interlocks to prevent parallel connections across sources. Static Uninterruptible Power Supply (UPS) battery systems provide 5 minutes of autonomous runtime. This bridge power ensures uninterrupted operation while the PLC detects utility undervoltage events, initiates diesel generator startup, synchronizes the generators, and transfers the site load. Prior to the utility disruption, the facility had been placed in a temporary single-feed (1N) bridged maintenance posture on the primary utility. Circuit breaker feeder B was physically opened and key-interlocked (Locked Out Tagged Out) to allow for corrective repairs following issues identified during a quarterly generator load test on 14 Oct 2026. Consequently, primary utility feed A was supporting the total critical load while repairs were conducted on the B feeder pathway. **Root Cause:** On Monday, 19 Oct 2026 at 22:53 US/Pacific (Tuesday, 20 Oct 06:53 BST), the primary utility provider experienced an outage on primary utility feed A, caused by an external underground cable fault on the utility network outside the data center facility.   When the primary utility feed A was lost, the facility’s generator plant failed to receive a signal to automatically start and take critical load due to a design voltage-sensing and misconfiguration in the PLCs. The facility's static UPS battery banks carried the critical load as designed until their battery reserves depleted resulting in a complete power loss across data halls. The investigation of the PLC configuration identified the root cause as a misconfiguration of the PLC logic that did not verify both an undervoltage condition and physical breaker position for both utility feeders. Instead, the PLC undervoltage sensing inputs were wired upstream (line side) of the isolated utility feed B breaker. The PLC was programmed to verify whether voltage was present on the feeder before commanding a generator start. As the utility feed B remained energized upstream, both PLCs sensed live upstream voltage on the disconnected path. As a result, the PLC logic indicated that a healthy utility source was available, even though the primary and secondary distribution feeds were de-energized, and did not issue a start command to the generator plant.; The onsite facilities team attempted to execute a remote load transfer via the PLC; however, the system inhibited the action. Recognizing that the UPS battery reserves would be exhausted before further remote operations could be resolved, the team transferred the facility load to the standby utility source, restoring the critical load that was lost once batteries depleted during this process. Once utility power was restored via the standby utility source, and UPS batteries started recharging, the onsite facility teams and OEM vendors reconfigured and validated PLC functionality on both undervoltage and breaker status. After the power loss was initially detected, Google engineers began work to mitigate failover failures and prepare service recovery. Upon restoration of the utility source, UPS and generator capabilities, they began the process to re-enable services in europe-west2-b. ### Remediation and Prevention The sequence of events leading to customer impact was as follows: * **19 Oct 22:53 US/Pacific (20 Oct BST 06:53 BST) -** An electrical power disruption occurred at the data center facility hosting availability zone europe-west2-b, and a PLC (Programmable Logic Controller) startup fault prevented facility emergency generators from assuming the electrical load. Facility load continued to be supported by UPS battery banks until the batteries were depleted. * **19 Oct 23:00 US/Pacific (20 Oct 07:00 BST)** **Impact start -** As battery backups were exhausted, physical host servers, local storage infrastructure, and network aggregation hardware in availability zone europe-west2-b lost power, causing instances, database replicas, and worker nodes in that zone to become immediately unreachable. * **19 Oct 23:04 US/Pacific (20 Oct 07:04 BST) -** Google engineers were alerted to the disruption via automated monitoring systems and probers, which detected elevated API error ratios, job submission timeouts, and loss of infrastructure reachability in zone europe-west2-b. Engineering teams immediately mobilized to isolate the affected infrastructure and commence recovery. * **19 Oct 23:09 US/Pacific (20 Oct 07:09 BST) -** Regional traffic-routing mechanisms and client applications initiated automated failover toward available infrastructure in adjacent availability zones within the region. * Cross-zone remote procedure calls from regional service control planes directed to metadata and catalog components in the offline zone encountered timeouts, causing initial job submission stalls and API latency spikes. * The sudden influx of redirected query executions, high-availability database failovers, and compute workloads saturated available compute slots and processing capacity in other availability zones, creating elevated admission queues, delayed database failover completions, and intermittent 500 and 503 API errors across the region. * **Traffic Isolation:** Google engineers isolated the offline availability zone (europe-west2-b) by adjusting regional service routing away from the affected infrastructure, preventing cross-zone client requests from timing out against offline endpoints. * **Workload Reprioritization and Resource Safeguards:** Engineers adjusted scheduler allocations and capacity limits across unimpacted infrastructure to prioritize active customer reservations, reduce resource contention on execution slots, and relieve queue backlogs for regional workloads. * **19 Oct 23:54 US/Pacific (20 Oct 07:54 BST) Utility Power Restoration** **\-** Power supply from the standby utility source was restored and power restoration to the data hall began. * **20 Oct 00:20 US/Pacific (08:20 BST) Datahall Power Restoration** **\-** Utility power was re-established to the datahalls. Mains utility power normalized; power feed to data hall verified. Following this, the site operations and engineering teams focused on and completed a reset and tested the emergency backup generator automation controllers to restore facility power. * **20 Oct 00:40 US/Pacific (08:40 BST)** **\-** Clusters began to recover, cluster manager systems started rescheduling compute jobs.  * **20 Oct 00:45 US/Pacific (08:45 BST) \-** Network devices were back online.  * **20 Oct 00:50 US/Pacific (08:50 BST) \-** Due to the immediacy of power loss, storage devices with unclean shutdowns began recovery. Responders recognized this and chose not to restore services that would otherwise make this worse. Because of the large volume of storage devices involved, this process required a substantial period to finish prior to restoring service to customers. * **20 Oct 03:13 US/Pacific (11:06 BST)** **\-** Power redundancy was verified and the storage infrastructure was sufficiently restored to prepare the initiation of controlled traffic re-admission. The remaining storage systems continued recovery operations. * **20 Oct 03:45 US/Pacific (11:45 BST) Controlled Traffic Re-admission** **\-** Once system health and storage integrity were verified, engineers executed gradual, controlled traffic re-admission back to zone europe-west2-b allowing accumulated job backlogs to clear smoothly. * **20 Oct 04:11 US/Pacific (12:11 BST)** **\-** Google Cloud Platform services and APIs were made fully available to customers. Some Google Compute Engine virtual machines were still not yet available. * **20 Oct 04:29 US/Pacific (12:29 BST) \-** Regional services and backend compute management systems were fully undrained, marking the end of core platform-level disruption. * **20 Oct 05:08 US/Pacific (13:08 BST) Majority Workload Recovery** **\-** GCE virtual machines were 99.5% operational and healthy, and creating new VMs was fully supported. Service availability was restored for most customer workloads, with resolution confirmed for the majority of users across Google Cloud Platform services in the region. Following the recovery of a small tail of remaining isolated workloads, the closure notification for the incident was posted by 07:03 US/Pacific (15:03 BST). Google is committed to preventing a repeat of this issue in the future and is completing the following actions: **Data Center Action Items:** * Restoration of normal utility configuration (both A & B feeds) * Utility provider to locate the damaged cable fault, using low-frequency radar penetration testing procedures. **\[Completed 26 Oct\]** * Utility provider to send on-site engineers to repair the cable fault and restore the impacted primary utility feed A source. **\[Estimated Completion Date 30 Oct\]** * Onsite Operations teams with a controlled method of procedure (MOP) to transfer the facility to its primary utility source (feeds A and B) from standby utility feed through coordinated switching with the utility provider **\[Estimated Completion Date 31 Oct\]** * Generator confidence testing * Full generator load transfer tests with utility power cutover of the active utility feed.

During the initial phase from 23:00 to 04:29 US/Pacific (07:00 to 12:29 BST) (duration 5 hours, 29 minutes), customers experienced unavailability of zone-scoped resources in products, including: * **Compute Engine** \- VM instances, zonal MIGs, unmanaged instance groups, zonal NEGs, sole-tenant node groups, zonal reservations, target instances, zonal API operations.  * **Persistent Disk / Hyperdisk** \- Zonal PD, zonal Hyperdisk, Hyperdisk storage pools, instant snapshots. * **GKE \-** Zonal clusters (control plane), node pool nodes in \-b, PVs on zonal disks. * **Cloud SQL \-** Non-HA instances, read replicas in \-b. * **AlloyDB \-** Basic (non-HA) primaries in \-b. * **Bigtable \-** Single-cluster instances in \-b. * **Other products with affected zonal resources:** Cloud Batch, Cloud Build, Cloud Storage, Cloud Workstations, Composer, Dataproc, Filestore, Managed Lustre, Migrate to VMs, NetApp Volumes, Pub/Sub Lite, Vertex AI Workbench, VMware Engine. The unavailability of those resources scoped to a zone that undergoes disruption is working within the design of a zonally-scoped system. Requests made to these resulted either in a timeout or error code during the disruption. Any workloads and resources hosted entirely within europe-west2-b became unreachable due to this event. Google Compute Engine's zonal resources such as VMs require customers to provision failover or cross-zone recovery resources if needed, and to set up a recovery mechanism that matches their needs. Some failovers were unsuccessful due to capacity constraints and difficulty in replicating the underlying storage mechanism.  Following platform service restoration, some customer workloads running on Compute Engine instances as well as products that rely on Compute Engine experienced a longer recovery. By 04:46 US/Pacific (12:46 BST) new Virtual Machine creation resumed and by 05:08 US/Pacific (13:08 BST) over 99% of Compute Engine Virtual Machines were in a healthy state. Any remaining customers that were experiencing Virtual Machine problems were directed to file a customer support case as per normal procedure. While the physical power outage was isolated strictly to data center facilities in zone europe-west2-b, some customers running workloads in unimpacted zones (europe-west2-a and europe-west2-c) or across regional architectures also experienced unexpected impact. The primary causes of impact outside of zone europe-west2-b were: 1\) Instantaneous demand surges on neighboring zones (a and c) and 2\) Control-plane dependencies across zonal boundaries Affected products included: AlloyDB, Apigee Infra and Apigee Edge, BigQuery, Cloud Dataflow, Cloud Pub/Sub, Cloud SQL, Google Compute Engine, Google Kubernetes Engine, Looker, Regional Persistent Disk, Vertex AI Prediction, and Cloud Speech-to-Text. These services experienced unexpected degradation and failover issues driven by sudden compute capacity exhaustion from surging demand, and control-plane API timeouts. Customers would have experienced the inability to create, update, or delete some regional resources during this period. This was not a full regional control-plane outage, but certainly a degraded state. Multi-zonal and regional services that spanned across the europe-west2 region experienced elevated latency, transient API errors (such as HTTP 500 and 503 errors), and task admission queuing as failover traffic concentrated onto unimpacted regional resources and cross-zone calls to offline components timed out.  Storage write operations in the region experienced a transient error rate during the initial failover period, and regional query admission queues temporarily peaked before rapidly subsiding as capacity re-balanced. We did not identify any impact of the outage outside of the europe-west2 region. The following Google Cloud Platform services experienced impact within europe-west2: * AlloyDB for PostgreSQL * Apigee * BigQuery Data Transfer Service * Cloud Data Fusion * Cloud Filestore * Cloud Firestore * Cloud Load Balancing * Cloud Memorystore * Cloud NAT * Cloud Run * Cloud Spanner * Cloud Workstations * Datastream * Dialogflow CX * Google App Engine * Google BigQuery * Google Cloud Bigtable * Google Cloud Dataflow * Google Cloud Dataproc * Google Cloud NetApp Volumes * Google Cloud Pub/Sub * Google Cloud SQL * Google Cloud Storage (GCS) * Google Compute Engine (GCE) * Google Kubernetes Engine (GKE) * Google SecOps (Security Information and Event Management \[SIEM\] and Security Orchestration, Automation, and Response \[SOAR\]) * Looker (Google Cloud core) * Looker Studio * Managed Airflow (Google Cloud Composer) * Managed Service for Apache Kafka * Memorystore for Memcached * Memorystore for Redis * Memorystore for Redis Cluster * Memorystore for Valkey * Network Connectivity Center * Persistent Disk * Private Service Connect * Speech-to-Text * Virtual Private Cloud (VPC) * VMWare engine ----------

      ## Raport preliminar de incident Ne cerem scuze sincer pentru întrerupere acest incident cauzat afacerii tale. Ştim cât de mult vă bazaţi pe Google Cloud şi regretăm impactul asupra productivităţii dumneavoastră. Ne străduim să abordăm cauza fundamentală şi să prevenim acest lucru în viitor. Vă rugăm să rețineți, aceste informații se bazează pe cele mai bune cunoștințe ale noastre la momentul postării și sunt supuse schimbării pe măsură ce ancheta noastră continuă. Un raport final de incident cu acţiuni preventive va fi postat după finalizarea investigaţiei noastre. Dacă ați avut un impact în afara celor enumerate mai jos, accesați Google Cloud Support folosind [https\://cloud.google.com/support] [https://cloud.google.com/support] ## Data/ora emisiunii (Tot timpul US/Pacific) Incident Start: 08 octombrie 2026 04:00 End incident: 08 octombrie 2026 16:30 Durata: 12 ore, 30 minute ## Rezumat Joi, 08 octombrie 2026, Google Cloud Storage a experimentat rate ridicate de scriere și de scriere a erorilor în regiunea ne-central1 pentru o durată de 12 ore, 30 minute. Suntem luați măsuri imediate pentru a asigura acest lucru nu se întâmplă din nou. ## Preliminary Root Cause Google Cloud Storage se bazează pe o arhitectură foarte distribuită pentru procesarea și stocarea datelor primite. În timpul ferestrei incidentului, nodurile specifice de stocare din regiunea ne-central1 au cunoscut un deficit de capacitate localizat. Secvența evenimentelor care au condus la impactul asupra clienților a fost următoarea: * O optimizare de sortare a traficului destinat să abordeze constrângerile de capacitate localizate a cauzat epuizare severă a resurselor pe noduri specifice de stocare backend în regiunea afectată. * Această epuizare de resurse a cauzat servicii de suport manipularea ingestiei de date obiect pentru a începe sincronizarea. * Ca urmare, cererile de upload şi scriere primite direcţionate către aceste noduri au avut latenţă ridicată şi nu au reuşit să se finalizeze, ceea ce a dus la apariţia unor erori către clienţi. * În același timp, o problemă separată cu serviciul de bază de date a contribuit la erori suplimentare de procesare a metadatelor în timpul unei porțiuni din fereastra incidentului. Inginerii Google au început o analiză completă a cauzelor profunde (RCA) și vor furniza informații suplimentare după ce sunt disponibile. ## Remediation Problema a fost detectată iniţial de echipele de inginerie Google care monitorizau activ telemetria sistemului încă de la începutul perioadei incidentului. Pentru a atenua problema, inginerii Google au executat următoarea strategie pas cu pas: * Inginerii au încercat inițial să aloce dinamic capacitatea de urgență suplimentară regiunii afectate, dar acest lucru a fost blocat de limitele de capacitate regională sistemice. * Pentru a diminua presiunea imediată, inginerii au drenat selectiv traficul din nodurile de stocare cele mai supraîncărcate. * O schimbare de configurare a fost implementată pentru a dezactiva optimizarea sortarea traficului, reducând în mod semnificativ resursele de pe platforma de stocare. * Pentru emisiunea concomitentă de metadate, inginerii au rulat o actualizare recentă a bazei de date de metadate. Odată ce nivelurile de trafic stabilizate și utilizarea resurselor au revenit la nivelurile normale de bază, nodurile drenate anterior au fost restabilite în serviciu activ, restabilind cu succes operațiunile normale. ## Descriere de impact Pe 08 octombrie 2026, de la 04:00 până la 16:30 US/Pacific, clienții care utilizează regiunea noastră centrală1 au experimentat rate ridicate de latență și eroare în timpul operațiunilor de încărcare și scriere Cloud Storage. * Clienții au observat în primul rând HTTP 503 Erori UNAVAILBILE pe operațiunile WriteObject și timeout-side client. * În acest interval de timp a fost observat şi un impact minor asupra operaţiunilor de citire. * Operaţiunile Cloud Storage în toate celelalte regiuni, precum şi toate celelalte servicii Google Cloud, au rămas neafectate de acest eveniment specific.

      ## Incident Report ## Data/ora emisiunii (Tot timpul US/Pacific) **Incident First Occurrence** Incident Start: 08 octombrie 2026 04:00 End incident: 08 octombrie 2026 16:30 Durata: 12 ore, 30 minute ** Incident Recurence ** Recurence Start: 09 octombrie 2026 04:05 Sfârşitul recurenţei: 09 octombrie 2026 09:46 Durata: 5 ore, 41 minute ** Durata totală:** 18 ore, 11 minute ## Rezumat Joi, 08 octombrie 2026, Google Cloud Storage a experimentat rate ridicate de scriere și de scriere a erorilor în timpul efectuării operațiunilor de încărcare sau de scriere în regiunea ne-central1 pentru o durată de 12 ore, 30 minute. Aceasta a fost urmată de o recurență vineri, 09 octombrie 2026 în zona ne-central1-b pentru o perioadă de 5 ore, 41 minute. Suntem luați măsuri imediate pentru a asigura acest lucru nu se întâmplă din nou. ## Root Cause Google Cloud Storage se bazează pe o arhitectură foarte distribuită pentru procesarea și stocarea datelor primite. În timpul ferestrei incidentului, nodurile specifice de stocare din regiunea ne-central1 s-au confruntat cu un deficit de capacitate localizat din cauza traficului sporit. Secvența evenimentelor care au condus la impactul asupra clienților a fost următoarea: * O actualizare a configurației de optimizare a trierii traficului la nivelul de echilibrare a sarcinii Google Cloud Storage destinat să abordeze constrângerile de capacitate localizate a cauzat epuizare severă a resurselor pe noduri specifice de suport de stocare din regiunea afectată prin ocolirea accidentală a logicii standard de rutare a capacității, rezultând un dezechilibru grav al sarcinii. * În consecinţă, o mică fracţiune de noduri backend de stocare în regiunea noastră-central1 a primit o proporţie covârşitoare de trafic de scris primite, în ciuda capacităţii de servire reduse disponibile. Această concentrare a traficului a dus la epuizarea resurselor pe serverele afectate de backend, cauzând servicii de suport care manipulează ingestie de date cu obiecte pentru a începe sincronizarea. * Deoarece instanţele de bază nu au putut procesa volumul ridicat de cereri suficient de repede, cererile de upload şi scriere primite direcţionate către aceste noduri au experimentat latenţă ridicată şi nu a reuşit să completeze, ceea ce a dus la erori apărute clienţilor. * În același timp, o problemă separată cu serviciul de bază de date a contribuit la erori suplimentare de procesare a metadatelor în timpul unei porțiuni din fereastra incidentului. * Recurența emisiunii pe 9 octombrie a fost cauzată de o răsturnare incompletă a unei caracteristici de planificator de încărcare, care a rupt mecanismul de echilibrare a sarcinii și a supraîncărcat câteva noduri de stocare mai mici. ## Remediation and Prevention Problema a fost detectată inițial la 08 octombrie 2026 la 04:50 de către echipele de inginerie Google care monitorizau activ telemetria sistemului la începutul perioadei de incident. Pentru a atenua problema, inginerii Google au executat următoarea strategie pas cu pas: * Inginerii au încercat inițial să aloce dinamic capacitatea de urgență suplimentară regiunii afectate, dar acest lucru a fost blocat de limitele de capacitate regională sistemice. * Pentru a reduce presiunea imediată, inginerii au drenat selectiv traficul de la nodurile de stocare cele mai supraîncărcate. * O schimbare de configurare a fost implementată pentru a dezactiva optimizarea sortarea traficului, reducând în mod semnificativ resursele de pe platforma de stocare. * Pentru emisiunea concomitentă de metadate, inginerii au rulat o actualizare recentă a bazei de date de metadate. * În timp ce aceşti paşi au oferit uşurare temporară, o recurenţă a dezechilibrului de sarcină a necesitat continuarea redirecţionării traficului şi drenarea componentelor de stocare afectate. Incidentul a fost definitiv rezolvat atunci când ingineria a inversat complet modificarea configurației de echilibrare a sarcinii problematice, restaurând comportamentul anterior de rutare conștientă de capacitate și permițând traficului să distribuie uniform în regiune. Odată ce nivelurile de trafic stabilizate și utilizarea resurselor au revenit la nivelurile normale de bază, nodurile drenate anterior au fost restabilite în serviciu activ, restabilind cu succes operațiunile normale. ** Acțiuni preventive:** Pentru a ne asigura că această problemă nu reapare, punem în aplicare următoarele îmbunătățiri: - ** Rollouts de configurare Safe:** Actualizăm protocoalele de implementare pentru a ne asigura că modificările logice de echilibrare a sarcinii sunt validate riguros în regiunile alternative, mai mici, înainte de a fi introduse în regiuni mai mari, foarte utilizate. - ** Controle operaționale inteligente:** Îmbunătățim arhitectura de echilibrare a sarcinii de stocare pentru a aplica cu strictețe constrângerile de capacitate, asigurându-ne că logica de distribuție a traficului nu poate ocoli garanțiile prealabile și traficul de rută către clustere care nu dispun de suficiente resurse de servire. - **Resilient Scaling Logic:** Implementăm îmbunătățiri specifice pentru accelerarea circulației datelor interne în interiorul celulelor de stocare foarte utilizate, permițând sistemului să proceseze mai eficient datele și să gestioneze cu o mai mare rezistență piroanele de încărcare temporare. ## Descriere de impact Pe 08 octombrie 2026, de la 04:00 la 16:30 în regiunea noastră-central1 și 09 octombrie 2026, de la 04:05 la 09:46 în noi-central1-b zona, clienții au experimentat rate ridicate de latență și eroare în timpul operațiunilor de încărcare și scriere Cloud Storage. * **Upload & Write failings:** Clientii au observat in primul rand HTTP 503 erori nevazibile privind operatiunile WriteObject si timeout-urile clientilor. * **Cresed Write Latency:** Scrieţi operaţiuni care au reuşit să treacă prin latitudini mult mai mari decât în mod normal. * Operaţiunile Cloud Storage în toate celelalte regiuni, precum şi toate celelalte servicii Google Cloud, au rămas neafectate de acest eveniment specific.

Ştim cât de mult te bazezi pe Google Cloud şi regretăm impactul asupra mediului înconjurător. Ne străduim să abordăm cauza fundamentală şi să prevenim acest lucru în viitor. Vă rugăm să rețineți, aceste informații se bazează pe cele mai bune cunoștințe ale noastre la momentul postării și sunt supuse schimbării pe măsură ce ancheta noastră continuă. Un raport final de incident cu acţiuni preventive va fi postat după finalizarea investigaţiei noastre. Dacă ați avut un impact în afara celor enumerate mai jos, vă rugăm să accesați Google Cloud Support utilizând https://cloud.google.com/support ## Data/ora emisiunii (Tot timpul US/Pacific) **Incident Start**: 1 septembrie 2026 07:41 **Incident End**: 1 septembrie 2026 11:52 **Duraţie**: 4 ore, 11 minute ## Rezumat Marţi, 1 septembrie 2026, unii clienţi din noi-central1-b au experimentat degradarea serviciilor de reţea şi izolarea instanţelor pe o perioadă de 4 ore şi 11 minute. Clienților noștri ale căror afaceri au fost afectate în timpul acestei întreruperi, ne cerem sincer scuze. Acesta nu este nivelul de calitate și fiabilitate ne străduim să vă oferim, și luăm măsuri imediate pentru a îmbunătăți performanța și disponibilitatea platformei. ## Preliminary Root Cause Declanşatorul tehnic imediat pentru acest eveniment a fost dezactivarea fizică accidentală a cablurilor din fibră optică de reţea în timpul unei proceduri de întreţinere de rutină hardware. Un inginer efectua o actualizare programată a capacității pe routere datacenter care susțin o fracțiune de capacitate în zona ne-central1-b. Arhitectura rețelei pentru fiecare centru de date este proiectată cu redundanță pe mai multe dispozitive de rutare. Sistemul este conceput pentru a fi rezistent la toate defecțiunile unui singur dispozitiv sau ale unui singur drum, iar cele mai multe eșecuri duble sau triple nu afectează traficul clienților. Pentru a asigura acest lucru, dispozitivele și căile de fibre sunt separate fizic în fiecare centru de date, cu diverse surse de energie. O eroare de procedură a însemnat că acțiunea de întreținere fizică secvențial deconectat 100% de căi de fibre peste toate dispozitivele în 13 minute. Natura erorii, combinată cu viteza acțiunii, a împiedicat avertismentele de acțiune incorectă care ajung la inginer înainte de deconectare completă. Aceasta a dus la izolarea capacității de calcul în zona afectată de rețea. Clienții nu au reușit să ajungă la mașinile lor virtuale, iar acele mașini virtuale nu au putut stabili conexiuni în afara zonei lor. ## Remediation Problema a fost detectată imediat de sistemele automatizate de monitorizare a pierderilor de rețea, precum și de sonde proactive, care au angajat rapid echipele de inginerie a rețelei și de răspuns la incidente. Pentru a atenua impactul imediat al clienților, echipele de inginerie au mutat în mod activ traficul departe de infrastructura afectată, transferând automat traficul compatibil de muncă către o capacitate sănătoasă în altă parte a regiunii. În același timp, tehnicienii de operațiuni hardware de la fața locului au identificat legăturile optice deconectate și au resetat fizic fibrele. Odată ce legăturile fizice au fost complet restaurate, ratele fluxului de trafic s-au normalizat și traficul a fost redirecționat înapoi pentru a returna capacitatea de serviciu. ## Descriere de impact Marţi, 1 septembrie, între 07:41 şi 11:52 US/Pacific, o parte din zona centrală 1-b a suferit o degradare severă a reţelei şi izolarea resurselor. * **Multiple produse afectate:** Perturbarea rețelei către/dinspre o parte din noi-central1-b a avut un impact asupra mai multor produse GCP pentru unii clienți din zona respectivă. * **Rata de eroare:** Ratele de scădere a fluxului de trafic pentru resursele găzduite în zona afectată au ajuns la 100% în timpul vârfului incidentului, ceea ce a dus la mașini virtuale inaccesibile și pierderi ridicate de pachete. **Affected Services and Features** * ** Google Compute Engine:** Incapacitatea de a accesa mașini virtuale în exterior și incapacitatea VMS-urilor de a ajunge la resurse de la distanță. * **Google Kubernetes Engine:** Clustere regionale/zonale și noduri inaccesibile în zona afectată, ceea ce duce la întârzieri în recuperarea clusterelor. * **Cloud Run / Google App Engine:** Latență temporară piroane și în așteptare coadă avortează ca backend volumul de muncă automat evacuat și mutat la capacitate sănătoasă. Un subset de locuri de muncă în zona cu impact specific s-au confruntat cu degradare până la 11:52 SUA/Pacific. * ** Cloud SQL, SwaziDB for PostgreSQL, Cloud Spanner, Google Cloud Bigtable, Cloud Filestore:** Accesul la date și conectivitatea sunt separate pentru cazurile localizate strict în infrastructura afectată. * ** Virtual Private Cloud (VPC), Cloud NAT, Apigee, Google BigQuery, Google Cloud Dataflow, Looker, Google SecOps SOAR, Hybrid Connectivitate, Cloud Interconectează:** Pierderea de pachete de rețea ridicată, scade conectivitate, și API temporizări în zona afectată.

      ## Incident Report ## Rezumat Marți, 1 septembrie 2026, unii clienți din noi-central1 au experimentat degradarea serviciului de rețea și izolarea în instanță pe o perioadă de 4 ore și 11 minute. Clienților noștri ale căror afaceri au fost afectate în timpul acestei întreruperi, ne cerem sincer scuze. Acesta nu este nivelul de calitate și fiabilitate ne străduim să vă oferim, și luăm măsuri imediate pentru a îmbunătăți performanța și disponibilitatea platformei. ## Root Cause Evenimentul a fost declanșat de deconectarea fizică accidentală a cablurilor de fibră optică de rețea în timpul întreținerii de rutină hardware. Un tehnician efectua o actualizare programată a capacității pe routere de centru de date care susțin o fracțiune de capacitate în zona ne-central1-b și o mică fracțiune de capacitate în zona ne-central1-f. În timpul întreținerii hands-on, fibrele optice care conectează routerele centrului de date la materialul de rețea au fost deconectate și transmițătoarele optice au fost înlocuite cu un transmițător care suportă conectivitatea de înaltă densitate. Acest transceiver nu a fost compatibil cu transmițătorii încă în vigoare în tesatura centrului de date, cauzând o pierdere de conectivitate pentru fiecare fibră. Reţeaua este proiectată cu routere redundante în camere separate din centrul de date din aceeaşi clădire, astfel încât defecţiunea unui router să nu întrerupă serviciul. Întreținerea a fost menită să modernizeze un router într-o perioadă de câteva zile, cu diversiunea traficului la fiecare etapă și verificarea între etapele pe care rețeaua le-a revenit într-un stat pe deplin conectat. Cu toate acestea, o eroare de procedură în procesul de upgrade orchestrat manual a cauzat lista completă de înlocuitori de transceiver pe toate routere să fie emise la tehnician fără instrucțiuni pentru a secvenția de lucru un router la un moment dat. Fluxul de lucru de întreținere nu a inclus, de asemenea, etapele de verificare preconizate pentru om și software pentru detectarea perturbărilor nedorite. Ca urmare, tehnicianul a deconectat secvenţial toate căile de fibră prin dispozitivele afectate în 13 minute. Viteza și natura erorii au împiedicat avertismentele de acțiune incorectă să ajungă la inginer înainte de pierderea conectivității. În plus, nu a fost urmată o procedură permanentă de oprire dacă se detectează lumină pe orice cablu de fibră optică după deconectare. Aceasta a dus la izolarea capacității de calcul în zona afectată de rețea. Clienții nu au reușit să ajungă la mașinile lor virtuale, iar acele mașini virtuale nu au putut stabili conexiuni în afara zonei lor. ## Remediation and Prevention Problema a fost detectată imediat de sistemele automatizate de monitorizare a pierderilor de rețea, precum și de sonde proactive, care au angajat rapid echipele de inginerie a rețelei și de răspuns la incidente. Pentru a atenua impactul imediat al clientului, echipele de inginerie au mutat activ traficul departe de infrastructura afectată. În același timp, tehnicienii de operațiuni hardware de la fața locului au identificat legăturile optice deconectate și au reintrodus fizic transmițătoarele optice originale. Odată ce legăturile fizice au fost complet restaurate, ratele fluxului de trafic s-au normalizat și traficul a fost redirecționat înapoi pentru a returna capacitatea de serviciu. Google se angajează să prevină repetarea acestei probleme în viitor și completează următoarele acțiuni: * Consolidarea formării în noi-central1 regiune și la nivel global în jurul tehnicilor de întreținere în condiții de siguranță, inclusiv cerința obligatorie pentru a verifica dacă lumina este pe fiecare fibră neplugged. * Termina migrarea fluxurilor de lucru upgrade de rețea la un sistem de orchestrare complet secvențiat automat. Cele mai multe fluxuri de lucru regionale de rețea au fost finalizate în 2025, iar fluxurile de lucru interzonale sunt în curs de desfășurare. * Completați implementarea de stop de lucru alertare pentru acțiuni care duc la deconectarea neintenționată a cablurilor de fibră vie în centrele de date Google. * Completați implementarea sistemului automatizat care va muta traficul regional departe de zonele defecte, reducând timpul de la aproximativ 19 minute în acest caz la aproximativ 5 minute. ## Descriere detaliată a impactului Marţi, 1 septembrie, între 07:41 şi 11:52 US/Pacific, o parte din zonele ne-central1-b şi noi-central1-f s-au confruntat cu degradarea severă a reţelei şi izolarea resurselor. 1. Multiple produse afectate: intreruperea retelei catre/dinspre o parte din noi-central1-b si noi-central1-f a afectat toate produsele PCG interzonale pentru unii clienti din aceste zone. 2. Impact regional: Produsele regionale care utilizează capacitatea în centrul de date afectat au fost afectate până la diversiunea traficului a fost pe deplin în vigoare la ora 08:00 SUA/Pacific. Google Kubernetes Motor și Cloud Run / Google App Engine a avut impacturi mai lungi, discutate mai jos. 3. Rata de eroare: Ratele de scădere a fluxului de trafic pentru resursele găzduite în zona afectată au atins 100% în timpul vârfului incidentului, ceea ce a dus la mașini virtuale inaccesibile și pierderi ridicate de pachete. **Affected Services and Features** * Google Compute Engine: Incapacitatea utilizatorilor din partea afectată de noi-central1-b și noi-central1-f de a accesa mașini virtuale în exterior, și incapacitatea VMS de a ajunge la resurse de la distanță. * Cloud SQL, ALYDB for PostgreSQL, Google Cloud Bigtable, Cloud Filestore: Accesul la date și conectivitatea s-au întrerupt pentru cazurile localizate strict la infrastructura afectată. * Cloud Spanner, Cloud Firestore: Lift Remote Procurement Call (RCP) rate de eroare, scrie timeouts, și piroane de latență pentru cazurile nam5 mai multe regiuni din cauza conectivității tăiate la componentele care rulează în zona afectată. * Virtual Private Cloud (VPC), Cloud NAT, Apigee, Google BigQuery, Google Cloud Dataflow, Looker, Google SecOps SOAR, Hybrid Connectivitate, Cloud Interconnect: Lift Network Package Loss, conectivity drops, and API timeouts in the impacted zone. * Google Kubernetes Engine (GKE): Intre 07:40 si 09:15 US/Pacific pe 2026-09-01, clientii au experimentat erori si timeout-uri la cereri pentru avioanele lor de control al clusterelor GKE (Kubernetes API servers) in noi-central1. Acest lucru ar fi putut duce la eșecul operațiunilor Kubernetes API, noi sau actualizate. * Cloud Run / Google App Engine: latență temporară piroane și în așteptare coadă avortează ca backend volumul de muncă automat evacuat și mutat la capacitate sănătoasă. Un subset de locuri de muncă în zona cu impact specific s-au confruntat cu degradare până la 11:52 SUA/Pacific. ** Impactul clientului ** Clienții cu resurse găzduite în clusterele afectate specifice din cadrul nostru-central1-b și noi-central1-f au experimentat o pierdere completă a conectivității la rețea începând cu 07:41 US/Pacific. În acest timp, mașinile virtuale și serviciile asociate au devenit inaccesibile de pe internet și de pe alte regiuni Google Cloud, iar aceste resurse interne nu au putut iniția conexiunile de ieșire. Problema a fost detectată aproape imediat şi inginerii au luat măsuri de diversiune a traficului la 07:45 şi 08:00 SUA/Pacific pentru a reduce impactul asupra produselor regionale. Până la 08:50 SUA/Pacific, majoritatea conexiunilor fizice au fost restaurate și traficul a început să se recupereze, iar acțiunile de deturnare a traficului au fost eliminate la 09:19 SUA/Pacific. Recuperarea completă în aproape toate serviciile afectate și operațiunile pe termen lung au fost confirmate de 11:52 SUA/Pacific. Deoarece izolarea rețelei s-a limitat strict la clustere specifice din cadrul nostru-central1-b și al nostru-central1-f, implementarea multizonalelor utilizând corect redundanța în alte zone din centrul nostru1 a fost în mare măsură capabilă să ocolească eșecul fizic al hardware-ului și să continue să servească traficului. Clientii cu proiecte atat noi-central1-b cat si noi-central1-f nu ar fi vazut impact multizonale - cel mult una dintre zonele lor ar avea capacitate in centrul de date afectat.

      ## Addendum to Incident Report Acest addendum extinde descrierea detaliată a impactului din mesajul anterior. Deși doar două clustere într-un centru de date în noi-central1-b și noi-central1-f izolare de rețea cu experiență, au fost afectate și câteva produse regionale care depind de centrul de date afectat. Între 07:41 și 11:52 US/Pacific, marți, 1 septembrie 2026, au fost afectate următoarele produse: - **VMS motor Compute**: VMs rulează în centrul de date afectat pierdut conectivitate de rețea la resurse situate în afara centrului lor de date. Din perspectiva Compute Engine, acest incident a afectat doar un subset de VMS din noi-central1-b şi noi-central1-f. - **Zonal and Regional Products Based on Compute Engine** Produse cu dependențe de VMs în centrul de date afectate simptome experimentate, cum ar fi timeouts conexiune sau service disidente deoarece VMS-urile subiacente pierdut conectivitate de rețea. Exemple de produse care se bazează pe VMS motor Compute includ: Apigee, Cloud SQL, Ali DB pentru PostgreSQL, Fluxul de date, Cloud Filestore, și Looker. - **Google Kubernetes Engine (GKE) **: GKE clusters al cărui plan de control a avut dependențe de VMS-urile motorului de calcul în clusterele afectate au experimentat erori și temporizări atunci când administratorii sau nodurile au încercat să se conecteze la serverul API Kubernetes. În consecință, ar fi putut fi întârziate desfășurarea, operațiunile Kubernetes API ar fi eșuat, iar nodurile noi nu s-ar fi putut înregistra la planul de control (cauzarea întârzierilor operaționale ale rezervei de noduri). - **Cloud Run and App Engine:** Încărcăturile din regiunea noastră centrală1 s-au confruntat cu latență ridicată, 5xx erori de solicitare anulate și degradarea conectivității de ieșire. Pentru a preveni eșecurile severe ale cererilor, traficul a fost deviat către alte grupuri. Redirecționarea cererilor către alte grupuri a cauzat temporar latență ridicată sau erori în aceste grupuri. Odată ce grupul afectat a fost restaurat, cererea de volum de muncă pentru aceste noi platforme a creat o "turmă înăbușitoare" de inițializări concomitente de instanță. Această supratensiune bruscă a ocolit cachele calde şi a copleşit nivelele interne de servire a fişierelor, prelungind simptomele până când capacitatea de urgenţă a fost furnizată. - ** Alte API și servicii Google**, în noi-central1 sau într-o multi-regiune care ne include pe noi-central1, au fost afectate în cazul în care acestea au avut dependențe de sarcinile software în clusterele afectate și nu au fost în măsură să utilizeze sarcini software într-un grup neafectat. Simptomele au inclus timeout-uri de conectare sau indisponibilitatea serviciului. Exemple de alte Google API și servicii sunt: Google Cloud Bigtable, BigQuery, Google SecOps SOAR, Cloud Spanner și Cloud Firestore. Pentru unele servicii, simptomele s-au limitat la piroane temporare de latență și la indisponibilitatea serviciilor până când volumul de muncă a trecut la grupuri neafectate. - **Private Service Connect**: Clienții (în orice regiune) au avut probleme de conectivitate care au implicat criterii de conectivitate ale COPS cu dependențe în noi-central1, în circumstanțe specifice: - criteriile de evaluare ale PSC pentru Google API au fost afectate în același mod ca și în secțiunea Google API și servicii. - Criteriile de evaluare ale PSC de către producător/consumator au fost afectate în cazul în care producătorul avea balanţe de sarcină sau VM-uri de suport în clusterele afectate de noi-central1. - **Hybrid Connectivity**: Some Cloud Router, Cloud VPN, and Cloud Interconectează atașamentele VLAN în noi-central1 au fost afectate în circumstanțe specifice: - Cloud Router BBP sarcini software pentru unele Router Cloud în noi-central1 experimentat un eveniment de întreținere Cloud Router în cazul în care sarcinile lor software BBP au fost difuzate în clusterele afectate. - Software-ul de tunel VPN cloud rulează în clusterele afectate pierdut conectivitate de rețea. Acest lucru a cauzat unele tuneluri VPN Nor în noi-central1 să meargă în jos până când o sarcină tunel de înlocuire într-un grup diferit a fost atribuit. - Resursele (în orice regiune) trimiterea pachetelor prin intermediul cloud Interconectează atașamentele VLAN în noi-central1 ar fi putut avea probleme intermitente de conectivitate în anumite situații în care fluxurile de rețea nu erau deja programate. - **Envoy-based charge balancers and other products**: Balansorii de sarcină și alte produse care au depins de sarcinile gestionate de Envoy ale unui subnet exclusiv proxy în noi-central1 s-au confruntat cu probleme de latență sau conectivitate în cazul în care în grupurile afectate s-au desfășurat suficiente sarcini de mesagerie. Următoarele produse au fost afectate: - balansatoare regionale de sarcini pentru aplicaţii externe în noi-central1 - balansoare regionale interne de sarcini pentru aplicaţii în noi-central1 - balansatoare interne de sarcini pentru aplicaţii în regiune cu proxime în noi-central1 - Reţeaua proxy externă regională în noi-central1 - Reţeaua internă proxy regională în noi-central1 - Reţeaua interregională de proxy cu proxies în noi-central1 - Secure Web Proxy în noi-central1

      # Preliminary Incident Report We sincerely apologize for the disruption this incident caused to your business operations. Recognizing your reliance on Google Cloud, we express our sincere regrets for any operational impact experienced. Our engineering teams are actively addressing the underlying root cause to prevent future recurrences. Please note that the information provided herein reflects our current understanding as of the time of publication and remains subject to revision as the investigation progresses. A comprehensive Incident Report detailing preventive measures will be issued upon conclusion of our inquiry. If you have experienced impact outside of what is listed below, please reach out to Google Cloud Support using https://cloud.google.com/support. ## Date/Time of the Issue (All time US/Pacific) * Incident Start: 20 August 2026 08:00 * Incident End: 20 August 2026 10:22 * Duration: 2 hours, 22 minutes ## Summary On Thursday, 20 August 2026, multiple Google Cloud services encountered elevated latency, provisioning failures, increased error rates, and service degradations lasting for a duration of 2 hours and 22 minutes. ## Preliminary Root Cause The disruption originated during scheduled fiber optic maintenance, which unexpectedly compromised network capacity between data centers within the us-west1 region. Automated rerouting mechanisms failed to properly redistribute traffic to alternate capacity, resulting in network congestion as volumes exceeded available bandwidth in the affected area. This underlying network degradation subsequently impacted higher-level service components through request throttling, increased latency, and cascading retries. Consequently, both control plane operations and data plane requests failed to execute successfully across several dependent Google Cloud services, producing the observed latency and elevated error rates. ## Remediation Internal monitoring alerted Google engineers to the incident, confirming that multiple services across us-west1 were affected. To mitigate the immediate operational impact, engineers initiated traffic draining protocols, re-routing service workloads away from the degraded network infrastructure. Following the restoration of inter-campus network capacity and the resolution of the core issue, engineers systematically restored traffic to the us-west1 region and confirmed service normalization. Long-term engineering solutions are currently being finalized and assigned to address the root cause and strengthen system resilience regarding fiber maintenance procedures. ## Description of Impact On Thursday, August 20, between 08:00 and 10:22 US/Pacific, Google Cloud customers in the us-west1 region encountered elevated latency, provisioning failures, and increased error rates. * Proportionate Impact / Error Rates: The precise scope of impact—including the proportion of affected projects and applications—and detailed error metrics will be published in the comprehensive Root Cause Analysis, as the reduced capacity caused request throttling, latency spikes, and increased retry volume. * Scope Exclusion: Services and workloads operating in regions other than us-west1 remained fully operational and unaffected. **Affected Services and Features** The following services experienced elevated latencies and/or increased error rates, across their respective data planes and control planes: * AlloyDB * Apache Kafka * Apigee Edge Public Cloud * Apigee X * Artifact Registry * BigQuery & BigQuery Data Transfer Service * Cloud Build * Cloud Data Fusion * Cloud Dataflow * Cloud Filestore * Cloud Key Management Service (KMS) * Cloud Monitoring * Cloud Run * Cloud SQL * Contact Center AI Platform * Dataproc Metastore * Google App Engine * Google Cloud Bigtable * Google Cloud Pub/Sub * Google Cloud Storage (GCS) * Google Compute Engine (GCE) * Google Kubernetes Engine (GKE) * Identity and Access Management (IAM) * Managed Airflow (Cloud Composer) *Managed Service for Apache Spark (Dataproc) Persistent Disk

      # Incident Report ## Summary On Thursday, 20 August 2026, from 08:00 to 10:22 US/Pacific (15:00 to 17:22 UTC), multiple Google Cloud services in the us-west1 region experienced elevated latency, provisioning failures, increased error rates, and widespread service degradations for a total duration of 2 hours and 22 minutes. The incident impacted a wide range of core services — including Persistent Disk, Google Kubernetes Engine, Google Compute Engine, Cloud Run, Google Cloud Bigtable, Cloud Storage, and Identity and Access Management — across both control plane operations and data plane requests. We sincerely apologize for the disruption this incident caused to your business operations and critical workloads. We recognize the vital role Google Cloud plays in supporting your organization, and we deeply regret the impact on your business operations and critical workloads. Engineering and infrastructure teams are actively implementing measures to address the root causes and strengthen network resiliency to prevent recurrences in the future. Specifically, teams are monitoring recovery progress, refining safety checks for planned optical maintenance, and optimizing regional traffic routing mechanisms to safeguard against unexpected capacity constraints. ## Root Cause The disruption originated during scheduled fiber optic maintenance, which unexpectedly compromised network capacity between data centers within the us-west1 region. Automated rerouting mechanisms failed to properly redistribute traffic to alternate capacity, resulting in network congestion as volumes exceeded available bandwidth in the affected area. This underlying network degradation subsequently impacted higher-level service components through severe packet loss, request throttling, and increased latency across inter-campus dependencies. Core infrastructure services, including Spanner Paxos consensus and the Unified Metadata Server (UMS), experienced significant latency spikes, which cascaded into timeouts and elevated error rates for downstream dependent products such as Cloud Storage, Cloud IAM, Persistent Disk, and Google Kubernetes Engine. Consequently, both control plane operations and data plane requests failed to execute successfully across multiple Google Cloud services in us-west1 throughout the duration of the incident. ## Remediation and Prevention Internal monitoring systems initially detected widespread service anomalies and alerted Google engineers, who promptly confirmed that multiple core services operating across the us-west1 region were severely impacted. In response to the immediate operational risks, engineering teams promptly executed emergency traffic draining protocols to reroute active service workloads away from the compromised inter-campus network infrastructure and minimize further customer disruption. Once teams restored inter-campus fiber network capacity, engineers systematically reintroduced production traffic back to us-west1 through controlled validation stages, ultimately confirming full service normalization across all impacted platforms. Longer term engineering remediations and architectural enhancements are actively being finalized and assigned to owning teams. Key focus areas include reforming scheduled maintenance protocols, establishing stricter safety checks and circuit redundancy requirements prior to routine maintenance, and refining automated regional traffic failover mechanisms to automatically handle sudden capacity degradation without incurring severe network congestion. ## Detailed Description of Impact On Thursday, August 20, between 08:00 and 10:22 US/Pacific, Google Cloud customers in the us-west1 region encountered elevated latency, provisioning failures, and increased error rates. * **Impact / Error Rates:** The reduced capacity caused request throttling, latency spikes, and increased retry volume. * **Scope Exclusion:** Services and workloads operating in regions other than us-west1 remained fully operational and unaffected. **Affected Services and Features** The following services experienced elevated latencies and/or increased error rates, across their respective data planes and control planes: * AlloyDB * Apache Kafka * Apigee Edge Public Cloud * Apigee X * Artifact Registry * BigQuery & BigQuery Data Transfer Service * Cloud Build * Cloud Data Fusion * Cloud Dataflow * Cloud Filestore * Cloud Key Management Service (KMS) * Cloud Monitoring * Cloud Run * Cloud SQL * Contact Center AI Platform * Dataproc Metastore * Google App Engine * Google Cloud Bigtable * Google Cloud Pub/Sub * Google Cloud Storage (GCS) * Google Compute Engine (GCE) * Google Kubernetes Engine (GKE) * Identity and Access Management (IAM) * Managed Airflow (Cloud Composer) * Managed Service for Apache Spark (Dataproc) * Persistent Disk The regional incident in us-west1 followed a structured three-phase recovery dictated by platform dependency layers: While core platform connectivity and live request serving were restored by 10:22 US/Pacific, certain services took additional time to fully recover due to asynchronous backlog processing and localized control-plane state reconciliation for a very small set of customers. For event-driven and pipeline services, inbound error rates dropped to 0 immediately, but some operations experienced elevated latency while workers processed through backlogs accumulated during the outage, clearing later for Cloud Pub/Sub, Cloud Build & Deploy, Cloud Dataflow, and Cloud Storage lifecycle deletions. Concurrently, while primary read/write traffic was healthy across the region, specific long-running lifecycle workflows required extra time to clear locks and reconcile distributed state machines. Compute Engine VM provisioning in zone us-west1-c and Cloud Filestore control plane instance allocation locks and resource validation checks took longer to normalize across regional storage backends.

      # Preliminary Incident Report We sincerely apologize for the disruption this incident caused to your business. We know how much you rely on Google Cloud, and we regret the impact on your productivity. Please note, this information is based on our best knowledge at the time of posting and is subject to change as our investigation continues. A final Incident Report with preventative actions will be posted once our investigation is complete. If you have experienced impact outside of what is listed below, please reach out to Google Cloud Support using https://cloud.google.com/support. ## Date/Time of the Issue (All time US/Pacific) **Google Cloud VMware Engine Impact:** - Start: 15 July 2026 17:09 - End: 16 July 2026 2:33 - Duration: 9 Hours, 24 Minutes **Google Cloud NetApp Volumes Impact:** - Start: 15 July 2026 16:39 - End: 16 July 2026 01:10 - Duration: 8 Hours 31 Minutes **Bare Metal Solution Impact:** - Start: 15 July 2026 18:37 - End: 16 July 2026 07:34 - Duration: 12 Hours 57 Minutes ## Summary On Wednesday, 15 July 2026, Google Cloud VMware Engine, Bare Metal Solution, and Google Cloud NetApp Volumes experienced service interruptions for a total duration of 14 hours, 55 minutes. We are taking immediate steps to ensure this doesn’t happen again. ## Preliminary Root Cause A regional data center hosting services in europe-west4-a experienced a loss of utility power and subsequent cooling capacity. The sequence of events leading to customer impact was as follows: - An electrical fault occurred on the utility grid upstream of the data center, disrupting the electrical distribution gear and cooling equipment. - The loss of cooling infrastructure resulted in ambient temperatures rising rapidly within the affected data halls. Host servers, storage clusters, and network switches were shut down to prevent equipment damages due to the extreme heat. - The high temperatures in the data hall resulted in disruption to customer workloads and control plane operations across the affected services. Google engineers have begun a full root cause analysis and we will provide additional information once it is available. ## Remediation Google engineering teams were alerted to the issue via automated temperature and hardware unreachability telemetry starting at 16:39 US/Pacific. Engineers collaborated with the third-party facility provider to safely restore primary utility power and cooling systems, returning ambient room temperatures to safe operational levels. With the environment stabilized, field support engineers and remote teams systematically booted and verified the server hosts, storage nodes, and network fabric in a controlled sequence. Automated recovery playbooks were executed to restore underlying network switches and routing infrastructure, allowing storage appliances and compute clusters to be brought back online and verified for health. The underlying infrastructure has been fully recovered, and normal operations have been successfully restored. ## Description of Impact On 15 July 2026 from 16:39 to 16 July 2026 07:34 US/Pacific, customers experienced service disruptions across several products in europe-west4-a zone: - **Google Cloud VMware Engine:** Customers lost connectivity to their private clouds and workloads as foundational hosts and network switches were powered off for thermal protection. - **Bare Metal Solution:** Customers experienced connectivity loss to their database servers and storage appliances as the underlying hardware was powered down. - **Google Cloud NetApp Volumes:** Customers in the STANDARD, PREMIUM, and EXTREME service levels were unable to access their storage volumes. Control plane operations, including the creation of new storage pools, volumes, and backups, experienced failures in the affected region.

      ## \# Incident Report ## \#\# Summary On Wednesday, 15 July 2026, Google Cloud VMware Engine (GCVE), Bare Metal Solution (BMS), and Google Cloud NetApp Volumes (GCNV) experienced service interruptions for a total duration of 14 hours, 55 minutes. The root cause for this outage is a 3ms voltage drop in the power feed from the utility provider and subsequent utility breaker protective action. This incident was mitigated by the data center provider rectifying the failed systems followed by the Google engineering team restoring the services. ## \#\# Root Cause A regional data center hosting services in europe-west4-a experienced an upstream voltage transient affecting both utility power feeds A and B. During this event, the utility breakers on both A and B feeds tripped and initiated the transfer to the back-up power source DRUPS (Diesel Rotary Uninterruptible Power Supply). The transition of side B to DRUPS system was successful without any power interruption. The DRUPS back-up power system for side A failed to take over the facility load due to electrical component failures. The DRUPS failure to take over load initiated automatic transfer of the affected 3 rows from feed A to redundant power feed B. Rows 1 and 2 transferred to power feed B successfully. Row 3 failed to transfer to power feed B and experienced complete power loss due to an overload protection breaker trip. The root cause of the failed transfer on the affected row was identified as load deployment discrepancy which is under further investigation by Google engineering team. This resulted in loss of both redundant power feeds to the single row. During the voltage transient event, the server data hall experienced an increased temperature due to a cooling system failure. The chiller controller dropped offline during the voltage transient event, failing to signal the chilled water distribution pumps to restart and ultimately causing the chiller system A to shut down. The redundant source was not available due to known ongoing construction work at the facility. This resulted in the data hall temperatures reaching 44°C and subsequent shutdown of the affected data hall machines.

During the voltage transient event, the chillers maintained power but shut down because the distribution pumps failed to restart, resulting in no water flow. The pumps were manually switched from auto to hand mode to restore circulation and cooling. The facility team deployed an interim portable UPS to support the chiller controllers and prevent localized controller power loss. Upon confirmation of utility power restoration, the facility returned to utility power via automatic switching with the exception of two Remote Power Panels (RPPs), which required manual verification before restoration of power to affected server row. To provide full resiliency the facility team aligned a swing DRUPS unit to restore the redundant configuration on the A feed and is working on repairing the faulty DRUPS. To remediate the power loss at Row 3, once the electrical fault was confirmed to be fully isolated, teams reset the tripped breakers, successfully restoring both redundant power to the impacted server racks. Google is committed to preventing a repeat of this issue in the future and is completing the following actions: * Detailed investigation by the engineering team of the sequence of events that prevented transfer of load to DRUPS system and identified system improvements **\[ETA Aug 2026\].** * Determine and resolve the cause of overload conditions that caused power loss to Row 3 **\[ETA Aug 2026\].** * Perform investigation of chiller pump control system redundancy setup to ensure cooling system resiliency **\[ETA Sep 2026\].** * Implement improvements to facility system monitoring alerts for power events and configure early alert thresholds for cooling excursion detection. **\[ETA Aug 2026\].** * The GCVE engineering team is working to improve the automated triggering of shutdown during quickly evolving thermal runoff situations **\[ETA Oct 2026\]**. * The BMS engineering team is working with partner teams to update the incident classification and SLO definitions to improve personnel availability during major datacenter events **\[ETA Sep 2026\]**. * The GCNV engineering team is collaborate with the data center team to review incident handling SLA and runbooks, identify potential future occurrences and create playbooks to address/mitigate them, establish monthly joint emergency drill, and review if the Netapp cluster recovery process can be expedited **\[ETA Aug 2026\].** ## \#\# Detailed Description of Impact On 15 July 2026 from 16:39 to 16 July 2026 07:34 US/Pacific, customers experienced service disruptions across several products in europe-west4-a zone: * **Google Cloud VMware Engine**: Customers lost connectivity to their private clouds and workloads as foundational hosts and network switches were powered off for thermal protection. * **Bare Metal Solution**: Customers experienced connectivity loss to their database servers and storage appliances as the underlying hardware was powered down. * **Google Cloud NetApp Volumes**: Customers in the STANDARD, PREMIUM, and EXTREME service levels were unable to access their storage volumes. Control plane operations, including the creation of new storage pools, volumes, and backups, experienced failures in the affected region.

      ## Incident Report ## Summary On Tuesday, 14 July 2026 10:00 PT, Google Cloud VMware Engine (GCVE) Stretched Cluster customers in the australia-southeast2 and europe-west3 zones experienced inter-site communication failures. The disruption was traced to a network configuration update that introduced a conflict, causing inter-site communication failures, which triggered VMware Stretched Cluster failover events. Google engineers successfully mitigated the impact by rolling back the issue-causing configuration change and resetting the network state. We sincerely apologize for the disruption this incident caused to your business. We know how much you rely on Google Cloud, and we regret the impact on your productivity. We are working to address the root cause and prevent this from occurring in the future. ## Root Cause A network configuration update intended to prepare the cloud network infrastructure for new capabilities was deployed to the foundational network control plane. While the configuration payload itself was structurally valid, it exposed an implementation gap within the control plane's routing logic. This logical gap caused the underlying network hosts to misconfigure program routing tables. As a result, traffic destined for the private IP address space used by GCVE Stretched Clusters was dropped. Because Stretched Clusters rely on this private address space to establish routing sessions for inter-zonal connectivity, the traffic drops severed communications between the active zones of the clusters, triggering VMware High Availability (HA) failovers. Standard routing health-checking protocols, such as Border Gateway Protocol (BGP) and Bidirectional Forwarding Detection (BFD), remained fully functional because their control plane sessions run on separate, unaffected address spaces. Because the control plane remained healthy, standard failover mechanisms failed to detect that the selective private IP range used for inter-zonal data tunneling was being dropped. Automated safeguards did not block the deployment because the configuration passed initial payload validations. The impact only manifested once the update began routing data traffic through the specific affected IP range. ## Remediation and Prevention To stabilize the environment, engineers identified the working network paths and deployed configuration changes to reroute traffic and restore connectivity. GCVE Stretched Cluster inter-zonal connectivity was completely restored for all supported locations on Tuesday, 14 July 2026 at 20:40 US/Pacific. Google is committed preventing a repeat of this issue in the future and is completing the following actions: * **Expanded Testing:** We are adding more detailed GCVE network setups to our existing testing environments. This allows us to automatically test future network updates against these configurations before they go live. * **Service-Level Data Path Failover:** We are implementing additional service-level data path failover mechanisms that actively probe the specific data-tunneling traffic space. This will ensure a path failover is triggered if the data plane itself is degraded even when the BGP control plane remains functional. * **Detailed Alerting**: We are adding faster, more specific alerts for connection issues between zones. This builds on our current platform monitoring to catch minor disruptions early and speed up our response. * **Improved Cluster Resilience:** We are fine-tuning the cluster's high-availability and storage settings. This makes virtual machines more resilient to short network drops, preventing them from restarting unnecessarily if the main site is still healthy. * **Workload Resilience Alignment (Shared Responsibility):** We are proactively reaching out to customers utilizing non-vSAN replicated virtual machine configurations within Stretched Clusters. Because these workloads are pinned to a single zone without active cross-site replication, they cannot survive inter-site network disruptions. We are ready to assist customers in auditing their storage policies, adjusting Stretched Cluster configurations, and planning the secondary zone capacity required to enable robust high-availability failovers. ## Detailed Description of Impact On Tuesday, 14 July 2026 from 10:00 to 20:40 US/Pacific, customers utilizing GCVE Stretched Clusters in the affected zones (australia-southeast2, and europe-west3) experienced inter-site communication failures. For some customers, depending on their architecture, this disruption led to a VMWare HA event causing VM restarts/movement across zones as designed, host disconnects, VSAN alarms and intermittent access to VMware Management (vCenter/NSX Manager) components.

Affected customers may experience intermittent latency spikes due to demand exceeding capacity across Indian metros and regional ISPs. Media CDN customers may have experienced higher latencies than normal. Initial traffic mitigations have yielded positive results for some Cloud customers. We have restored a portion of Internet Edge peering capacity to reduce latency in the local Delhi metropolitan area. Further, we are augmenting out-of-region Internet Edge regional peering capacity in Chennai to provide additional load-balancing and redundancy to large ISPs in India (expected to be done by Wednesday, 2026-06-17 PDT). We have optimized capacity across network backbones to increase available headroom. Additionally, we have augmented our Delhi backbone capacity over the weekend. We will continue to closely monitor latency deviations and packet drops. We will provide our next update by Wednesday, 2026-06-17 at 17:00 PDT. **Symptoms** Customers may experience slightly elevated latency and non-optimal network routing into Google Cloud until the affected facility is fully restored. **Workaround** There is no workaround at this time.

      ## \# Incident Report ## \#\# Summary On Friday, 18 July 2025 07:50 US/Pacific, several Google Cloud Platform (GCP) and Google Workspace (GWS) products experienced elevated latencies and error rates in the us-east1 region for a duration of up to 1 hour and 57 minutes. **GCP Impact Duration:** 18 July 2025 07:50 \- 09:47 US/Pacific : 1 hour 57 minutes **GWS Impact Duration:** 18 July 2025 07:50 \- 08:40 US/Pacific : 50 minutes We sincerely apologize for this incident, which does not reflect the level of quality and reliability we strive to offer. We are taking immediate steps to improve the platform’s performance and availability. ## ## \#\# Root Cause The service interruption was triggered by a procedural error during a planned hardware replacement in our datacenter. An incorrect physical disconnection was made to the active network switch serving our control plane, rather than the redundant unit scheduled for removal. The redundant unit had been properly de-configured as part of the procedure, and the combination of these two events led to partitioning of the network control plane. Our network is designed to withstand this type of control plane failure by failing open, continuing operation. However, an operational topology change while the network control plane was in a failed open state caused our network fabric's topology information to become stale. This led to packet loss and service disruption until services were moved away from the fabric and control plane connectivity was restored. ## \#\# Remediation and Prevention Google engineers were alerted to the outage by our monitoring system on 18 July 2025 07:06 US/Pacific and immediately started an investigation. The following timeline details the remediation and restoration efforts: * **07:39 US/Pacific**: The underlying root cause (device disconnect) was identified and onsite technicians were engaged to reconnect the control plane device and restore control plane connectivity. At that moment, network failure open mechanisms worked as expected and no impact was observed. * **07:50 US/Pacific**: A topology change led to traffic being routed suboptimally, due to the network being in a fail open state. This caused congestion on the subset of links, packet loss, and latency to customer traffic. Engineers made a decision to move traffic away from the affected fabric, which mitigated the impact for the majority of the services. * **08:40 US/Pacific**: Engineers mitigated Workspace impact by shifting traffic away from the affected region. * **09:47 US/Pacific**: Onsite technicians reconnected the device, control plane connectivity was fully restored and all services were back to stable state. Google is committed to preventing a repeat of the issue in the future, and is completing the following actions: * Pause non-critical workflows until safety controls are implemented (complete). * Strengthen safety controls for hardware upgrade workflows by end of Q3 2025\. * Design and implement a mechanism to prevent control plane partitioning in case of dual failure of upstream routers by end of Q4 2025\. ## \#\# Detailed Description of Impact \#\#\# GCP Impact: Multiple products in us-east1 were affected by the loss of network connectivity, with the most significant impacts seen in us-east1-b. Other regions were not affected. The outage caused a range of issues for customers with zonal resources in the region, including packet loss across VPC networks, increased error rates and latency, service unavailable (503) errors, and slow or stuck operations up to loss of networking connectivity. While regional products were briefly impacted, they recovered quickly by failing over to unaffected zones. A small number (0.1%) of Persistent Disks in us-east1-b were unavailable for the duration of the outage: these disks became available once the outage was mitigated, with no customer data loss. \#\#\# GWS Impact: A small subset of Workspace users, primarily around the Southeast US, experienced varying degrees of unavailability and increased delays across multiple products, including Gmail, Google Meet, Google Drive, Google Chat, Google Calendar, Google Groups, Google Doc/Editors, and Google Voice.
