Users may be experiencing slowdowns across various functions of Trello including creating/deleting comments, editing cards, or creating new attachments. The team is actively working to fix the issue and will provide more updates within the hour.

The team has identified the root cause and is hard at working resolving this issue. Users will see problems creating/updating/deleting comments and loading the activity view for cards at this time. The rest of Trello's features should be working as normal. We will provide more updates within 2h.

Work by the Trello engineering team continues to restore functionality to comments and activity views. Next update will be posted within 4h or on a significant change. Thank you for your patience.

Work by the Trello engineering team continues to restore functionality to comments and activity views. Recovery of the affected systems is taking longer than anticipated. Next update will be posted within 4h or on a significant change. Thank you for your patience.

Trello is experiencing slowdowns and failures affecting comment operations, including creating and deleting comments. Users may also experience delays when loading activity views on cards, viewing attachments, using Power-Ups, or exporting boards. Some users are encountering errors when viewing specific cards. The team is working hard to restore full functionality and will provide another update within 3h.

Trello is experiencing slowdowns and failures affecting comment operations, including creating and deleting comments. Users may also experience delays when loading activity views on cards, viewing attachments, using Power-Ups, exporting boards and 'Updates' on home page. Our team is actively working on the resolution and will likely take up to 7 hours to restore the services back to full functionality. We will provide further update at this time, or earlier if we have additional information to share prior to this resolution.

Trello continues to experience slowdowns and failures that are affecting comment operations, including creating and deleting comments. Our teams continue to work on the issue resolution, while it is taking longer than expected. We will provide more updates within the next 8 hours or sooner once we have further information to share.

Our teams continue to work diligently on the mitigation. During this time, we recommend that you do not move or copy cards or lists between boards. For users whose boards are affected by this issue, you may create and delete cards and edit card descriptions as usual, but you will not be able to see comments or the detailed activity log of the cards. We estimate that the rebuild will take another 24 hours to complete. We will update this page as we have more information.

We want to provide more transparency regarding this incident given its duration. We were optimizing one of our largest databases, specifically the one storing comments and card activity. At the end of this process, a bug caused some database partitions to go live without their indexes. This means queries to those partitions are timing out, which is why approximately 40 percent of boards are experiencing failures. Your data is safe. Any comments added during this incident are being saved and will reappear once the process is complete. We are currently rebuilding the missing indexes. We have allocated significant compute resources to this task to move as quickly as possible, but the data volume is enormous. We estimate it will take approximately 20 more hours to reach full resolution. Most impacted features include, but are not limited to: - Comments (viewing, adding, notifications) - Activity views on cards - Attachments, Power-Ups, board exports - Home page / 'Updates' view - Search - Some cards showing 'Card Not Found' - Moving/copying cards or lists Please avoid moving or copying cards between boards for now. If your board is working normally, you can continue your work, as most boards remain unaffected. We know Trello is where your work lives and we are committed to getting everything back to normal. We will provide next update in eight hours or sooner as we make progress.

We are continuing to monitor the index rebuild process across all affected shards and will provide updates as each phase completes. We will provide next update in eight hours or sooner as we make progress.

Index rebuild is complete and functionality should be restored for users. We are aware that cards moved by users during the incident may be in an incomplete state and we are investigating solutions. We have no indication of data loss during the incident. We will continue to monitor and will provide the next updates in 4 hours or sooner.

Users should be experiencing restored functionality to their boards and cards. We are running scripts to replay actions that occurred during the incident. We will update once these are complete.

Users should be experiencing restored functionality to their boards and cards. The team continues to remediate potential outstanding data issues that occurred on Boards and Cards during the incident. Below is a list of remaining issues that may still be occurring, but we are currently working to resolve via processing on our end. These issues were caused by card moves between boards during the incident. - Missing card labels - Attachment restrictions not being enforced on moved cards - Checklist assignees that are not a member of the current board may incorrectly linger - Card assignees that are not a member of the current board may have incorrectly received due date reminders Please note that cards are safe to edit, but they may be excluded from certain restoration work if they are edited.

We greatly appreciate your patience as we work through these issues. We will provide another update when above issues are resolved. In the meantime, please reach out to our support team if you need further assistance.

# Summary On May 17th 2026 at 12:00 UTC a subset of Trello users experienced a degradation of some core functionality including but not limited to: issues with comments, viewing activity logs, accessing card details, board exports, Power-Ups, attachments, Home page updates, and search functionality. Some moved cards displayed 'Card Not Found' errors. These issues persisted for multiple days. Most of the issues encountered when interacting with Trello (commenting, viewing activity) were resolved by May 19 2026 at 08:31 UTC, however there was a lingering data integrity issue which manifested as “Card Not Found” errors when trying to open cards. >90% of these cards were repaired by May 28 at 17:20 UTC. The remainder took a little more time and were completely repaired by June 5th 2026 at 21:37 UTC. We wanted to share a more detailed analysis of the issues we encountered, as well as what we’re doing to ensure nothing similar happens in the future. # Root Cause The incident was caused by a bug in our database (MongoDB) which surfaced during a project to optimize the performance and scale of one of our largest collections. The affected collection contains card comments and other activity and is used across much of Trello’s functionality. The optimization project was to reshard the collection onto a new key. This allows us to eliminate a so-called “insert hot spot” which is where all newly created database entries end up on a single database partition (aka shard). After resharding, the load would be spread evenly across the various servers that make up the database cluster. This decreases latency and improves query performance for users. During the final stages of the resharding operation (which is a long-running, automated process), 12 of the 30 relevant shards ran out of disk space while building indexes. Rather than aborting the resharding process, the database bug caused the cluster to put the new database servers into rotation without their indexes, despite logs and metrics saying otherwise. Due to the enormous amount of data in this collection, having no indexes means that there is essentially no way to query for the data you want (i.e. “give me all comments for this card”) without performing an extremely slow and inefficient collection scan. # Remedial Actions Plan The first thing we did was initiate a full rebuild of all the database indexes for the collection. Unfortunately this takes a very long time to complete (multiple days) and is compute-intensive. We scaled all the database servers up in order to help the process move faster, however due to the single-threaded nature of this process, more compute did not equate to more speed. Additionally we enabled a database setting which caused all queries that would result in a full collection scan to fail-fast rather than drag on in the background and consume database resources before ultimately failing. This helped the parts of Trello that were still working stay responsive. Once the reindex process had completed, all functionality was restored. However, we discovered that cards which were moved to a different board during the rebuild were left in a broken state. Their activity logs and comments were essentially stranded on the old board while the card was now on the new board. This manifested as a “Card Not Found” error when trying to open such a card. The team moved into a new phase of writing code to safely remediate all of the remaining data issues in batches, with the final batch of fixes completing by June 5th 2026 at 21:37 UTC. # Next Steps We know that Trello is where your work lives and issues like this can cause a lot of disruption. To ensure we don’t run into this issue again in the future, the team is taking the following actions: - Working closely with our database vendor to ensure the original bug is fixed (update: the fix is shipping in the next version) - Working to create a standard set of tools and processes to ensure index rebuilds proceed as fast as possible in an emergency like this - Designing and implementing changes to make card move operations more atomic (either the whole operation succeeds, or the whole operation fails, rather than a partial failure)

We are investigating degraded performance of some Trello features. We will provide more details within the next hour.

Trello engineers are actively working on resolving issues that our users may be seeing around commenting on cards, deleting comments, and adding new attachments. Users may also find that recent changes to cards are not reflected in search results. We are continuing to work on it and will provide more updates within the hour.

The Trello team has identified and mitigated most of the issues with cards and comments. Users may still see delays in search indexing for short time while it catches up to realtime.

The team has resolved the previous issues and is now monitoring the system to ensure a full return to baseline. Search indexing is still approximately 1h delayed, but will be up to date shortly. Thank you for your patience

Search is now fully up to date for all users, and all issues with previous degraded functionality have been resolved.

### Summary On May 14, 2026, between 04:30 and 05:26 UTC, Atlassian customers experienced widespread service disruption across multiple Atlassian Cloud products. The issue was caused by a race condition in our internal deployment orchestration platform during a routine rollback operation of a core identity service in the us-east region. This race condition resulted in insufficient capacity for the identity service in the affected region which started returning errors to dependent products. The incident was detected within a minute by automated monitoring systems and mitigated in 56 minutes. ### **IMPACT** During the incident, customers attempting to access Atlassian Cloud products in the us-east region experienced authentication and permission failures and were unable to access services. Customers also experienced errors when accessing the support portal until Atlassian fell back to an alternate support method. This was caused by a core identity service in the us-east region becoming unavailable. Affected products included Atlassian Administration, Atlassian Analytics, Bitbucket, Compass, Confluence, Jira, Jira Product Discovery, Jira Service Management and Trello. Some users outside us-east may have been affected in certain scenarios. ### **ROOT CAUSE** The incident was caused by a race condition in our internal deployment orchestration platform during a routine rollback operation of a core identity service in the us-east region. This race condition resulted in insufficient capacity for the identity service in the affected region which started returning errors to dependent products. ### **REMEDIAL ACTIONS PLAN & NEXT STEPS** We know that outages impact your productivity. Atlassian is prioritizing the following actions to help prevent similar incidents in future: * **Refine deployment orchestration safeguards** * Harden our deployment platform to prevent similar race conditions or resulting capacity loss during a rollback operation. * Streamline mitigation steps when a service becomes unavailable in a region. * **Reduce cross-region impact** * Improve regional isolation and fallback handling so an issue affecting a single region is less likely to impact customers or product functionality in other regions. We recognise how critical reliable access to Atlassian products is for our customers' productivity, and we apologize to customers who were impacted by this incident. Thanks, Atlassian

We are experiencing issues with multiple Atlassian products. Our teams are investigating further and more updates including will be shared within 1 hour.

We have identified that the root cause of the issue is related to an infrastructure outage from our public cloud provider. We are working closely with them to mitigate this issue. We will provide further updates when they become available.

Our teams continue to work on mitigating the infrastructure outage from our public cloud provider. We will provide further updates when they are available.

We are continuing to work with our public cloud provider to mitigate this issue. We are starting to see some recovery in regions outside of Eastern USA, however, users globally may still be experiencing issues with certain product features. These are listed at the bottom of each product page.

The underlying issue in public infrastructure which affected asynchronous event processing has been mitigated and all the affected services are recovering. We are now working on clearing the backlog of queued events, which means some actions (such as notifications, automation triggers, and data syncs) may be in degraded state. We will continue to monitor and provide updates as the backlog is cleared.

We continue to monitor the situation as services recover. We are currently in the process of clearing the backlog of queued events. We will provide a further update in approximately one hour.

We are continuing to monitor for any further issues.

This incident has been resolved.

All dates and times below are in UTC unless stated otherwise. ### Summary On May 8, 2026 between 00:22 and 06:08, one of our hosting providers suffered a significant incident in a specific availability zone in prod-east which led to Atlassian customers experiencing degraded performance and delays of background operations and automation execution. The incident started on May 8, 2026 at 00:22 and was detected within 4 minutes by automated monitoring systems. Our teams worked to restore core access by 06:08. Final cleanup of backlogged processes and minor issues progressed in stages from there was completed iteratively by 19:15. ### **IMPACT** The primary infrastructure affected in this incident was the event processing pipeline in the prod-east region, which distributes events between Atlassian services and underpins background operations such as automation execution, search indexing, notifications, permission synchronisation. * Between 00:22 and 06:08, an infrastructure incident in our hosting provider triggered an ingestion failure in our event processing pipeline. * At 02:50, event ingestion was failed over to an unaffected availability zone, progressively restoring live event flows. * At 06:08, reliability for new ingestion in prod-east recovered to 100%. The remaining work was to drain the accumulated cross-region backlog of messages, which completed by 17:00. * By 18:48, Automation had processed their backlog of events that were created while processing **Automation** Between 00:22 and 02:50, customers with automation rules triggered by events originating from the prod-east region experienced a significant reduction in rule executions. During this window, event-triggered automation rules were not firing because the events that trigger them were not being delivered. Rule authoring, saving, and rules triggered manually, by schedules, or by webhooks were not affected. At 02:50, the event processing infrastructure failed over to an unaffected availability zone, restoring delivery of live events to Automation and allowing new event-triggered rules to begin executing normally. However, events generated during the impact window still needed to be replayed before delayed automations could be processed. Beginning at 08:28, upstream services replayed their queued events in a coordinated sequence, and all replayed events were processed by 18:48. During the replay window, customers may have experienced automation rules executing later than expected, a small number of rules reaching daily processing limits due to compressed replay, and time-sensitive rules not completing as expected if internal timeout thresholds were exceeded. **Jira and Jira Service Management** Between 00:22 and 02:50, customers with tenants hosted in the prod-east region experienced disruption to Jira and Jira Service Management event-driven features like automation, along with a short period of elevated errors during infrastructure failover. Core Jira experiences, including issue view, boards, and project navigation, remained available throughout the incident. Jira event delivery was affected by the primary impact, preventing downstream services from receiving issue lifecycle events. This affected automation rules triggered by Jira events, AI agent orchestration in Jira, notifications for issue updates and transitions, search indexing for newly created or modified issues, and event-driven integrations between Jira and other Atlassian products. At 02:50, the event processing infrastructure failed over to an unaffected availability zone, restoring delivery of new events. All events generated during the impact window were retained in a recovery queue and required replaying. This began at 08:28 and completed at 12:00. During the replay window, customers may have experienced automation rules executing later than expected, delayed notifications arriving hours after the triggering action, temporary gaps in search results for content created or modified during the impact window, and AI agent workflows not completing as expected where internal timeout thresholds were exceeded. **Confluence** Between 00:22 and 02:50, customers with tenants hosted in the prod-east region experienced disruptions to event-driven services in Confluence. This resulted in delays to search indexing, notifications, automation rule execution, and permission synchronisation. The underlying event processing infrastructure failed over to an unaffected availability zone, after which live Confluence operations resumed normally. However, events generated during the impact window were queued for replay, and some background services remained delayed until that replay and related validation work completed. Between 10:14 and 17:00, a bulk replay of all the queued tenant replay tasks was completed to restore data consistency. During and immediately after the replay window, customers may have experienced search results not reflecting content created or modified during the outage, delayed or missing notifications for page and comment activity, automation rules firing later than expected, and brief delays in permission synchronisation for tenants relying on incremental identity sync. **Bitbucket and Pipelines** Between 00:22 and 06:08, customers using Bitbucket and Pipelines experienced failures and degraded functionality across event-driven workflows. Core Git operations, including push, pull, and clone, were not affected and continued to operate normally throughout the incident. Automatic pipeline triggers initiated by push or pull request events were unavailable during the impact window. Merge queues, custom merge checks, Forge-based triggers, workspace permission changes, and some workspace provisioning flows were also affected. Customers using merge queues were unable to merge pull requests, and some pipeline steps failed because queued work contributed to elevated concurrency limits. At approximately 03:57, Pipelines was reconfigured to consume events through an alternative path, restoring automatic pipeline triggering. Merge queues, custom merge checks, Forge triggers, and other affected workflows were progressively restored as the underlying event processing infrastructure recovered. All Bitbucket and Pipelines services were confirmed fully operational by 06:08. After recovery, queued events were reviewed and replayed where safe to restore data consistency for billing, audit logging, and other background processes. **Identity Services** Between 00:22 and 02:50, customers with tenants hosted in the prod-east region experienced delays in the propagation of identity and group membership changes to downstream Atlassian products. Core identity operations, including authentication, login, and direct group management actions, were not affected and continued to function normally throughout the incident. The impact was limited to asynchronous, event-driven operations that depend on the event processing pipeline. This included delays in delivering group membership and user profile changes to products such as Jira and Confluence, which affected downstream permission synchronisation and crowd sync flows. A small number of SCIM-based identity synchronisation and site provisioning workflows also experienced temporary delays. After the event processing infrastructure recovered, backed-up identity and group directory events were replayed where required, restoring downstream consistency for affected products. No identity data was lost. Group membership changes, user profile updates, and provisioning-related events that occurred during the impact window were retained and processed after recovery. ### **REMEDIAL ACTIONS PLAN & NEXT STEPS** We know outages impact your productivity. While our monitoring and recovery processes helped us respond quickly, this incident highlighted opportunities to further strengthen resilience for event-driven services. We are prioritizing improvements that will: * **Enhance failover coverage** so critical event processing can recover more smoothly during infrastructure disruptions. * **Strengthen recovery handling** so replayed events can be processed more quickly. We apologize to customers whose services were impacted during this incident; we are taking immediate steps to improve the platform’s performance and availability. Thanks, Atlassian Customer Support

### **Summary** On Feb 9, 2026, between 07:12 UTC and 08:05 UTC, Atlassian customers were unable to access Trello. The event was triggered by Trello servers reaching maximum memory limits and a subsequent failure to automatically scale for the traffic. The incident was detected within 5 minutes by automated monitoring systems, engaging Trello teams for resolution. Two parallel mitigation efforts were undertaken to restore access: 1\) manual scaling to address concerns with high utilization of hosts, and 2\) temporarily limiting traffic from free customers. This intervention put Trello systems in a known good state with a total time to resolution of ~53 minutes. ### **IMPACT** The overall impact occurred on Feb 9, 2026 between 07:12 AM UTC and 08:05 AM UTC for Trello customers and caused service disruption for all customers, making Trello inaccessible during that time. Access was restored for paid users approximately 43 minutes after the onset, with full service restoration for free users 10 minutes later. ### **ROOT CAUSE** The issue was cause by increased memory requirements during the transition from the weekend to EU business hours, combined with Auto Scaling group scaling rules based on CPU utilization. Memory allocation on our instances outpaced the CPU usage, which caused processes to hit Out-Of-Memory \(OOM\) errors and crash before reaching CPU usage thresholds that would trigger the auto scaling policies. As a result, Trello went down and users received HTTP 502 errors until the incident was resolved. ### **REMEDIAL ACTION PLAN & NEXT STEPS** We know that outages impact your productivity. While we have a suite of automated infrastructure management in place, this specific issue required manual intervention to restore Trello access to users. To avoid repeating this type of incident, we are prioritizing the following remedial action items: * Pre-scale capacity before EU morning traffic - This change has already been introduced to prevent further incidents while we implement additional safeguards. * Adjust Trello’s Auto Scaling group settings - This change will ensure that unhealthy hosts will be replaced more rapidly and scaling policies will consider memory usage. * Refine Trello host memory commitments - This change will decrease the likelihood of memory overcommitment on hosts and associated OOM errors. * Increase isolation for OOM errors - This change will improve the ability for hosts to recover in the event of a single worker experiencing an OOM error. We apologize to customers whose services were impacted during this incident; we are taking immediate steps to improve the platform’s performance and availability. Thanks, Atlassian Customer Support

We have taken steps to mitigate the issue and are seeing recovery in the affected services. Our teams will continue to closely monitor the situation and are actively working to confirm that all services are fully restored. We will provide further updates as we make additional progress.

### Summary On **December 27, 2025**, between **02:48 UTC and 05:20 UTC**, some Atlassian cloud customers experienced failures in sending and receiving emails and mobile notifications. Core Jira and Confluence functionality remained available. The issue was triggered when **TLS certificates used by Atlassian’s monitoring infrastructure expired**, causing parts of our metrics pipeline to stop accepting traffic. Services responsible for email and mobile notifications had a critical path dependency on monitoring path leading to service disruptions. All impacted services were fully restored by **05:20 UTC**, around **2.5 hours** after customer impact began. ### IMPACT During the impact window, customers experienced: * **Outbound product email failures** \(notifications and other product emails did not send\). * **Identity and account flow failures** where emails were required \(e.g. sign‑ups, password resets, one‑time‑password / step‑up challenges\). * **Jira and Confluence mobile push notifications** * **Customer site activations and some admin policy changes** failing and requiring later reprocessing. ### ROOT CAUSE The incident was caused by: 1. **Expired TLS certificates** on domains used by our monitoring and metrics infrastructure caused by **misconfigured DNS authorization record** which prevented automatic renewal. 2. **Tight coupling of services to metrics publishing**, which caused them to fail when monitoring endpoints became unavailable, instead of degrading gracefully. ### REMEDIAL ACTIONS PLAN & NEXT STEPS We recognize that outages like this have a direct impact on customers’ ability to receive important notifications, complete account tasks, and operate their sites. We are prioritizing the following actions to improve our existing testing, monitoring and certificate management processes: * **Hardening monitoring and certificate infrastructure** * We are refining DNS and certificate configuration across our monitoring domains and strengthening proactive checks to detect and address failed renewals and certificate issues well before expiry. * We are also improving alerting on our monitoring and metrics pipeline. * **Decoupling monitoring from critical customer flows** We are updating services such as outbound email, identity, mobile push, provisioning, and admin policy changes so they no longer depend on metrics publishing to operate. If monitoring becomes unavailable, these services will continue to run and degrade gracefully by dropping or buffering metrics instead of failing customer operations. We apologize to customers impacted during this incident. We are implementing the improvements above to help ensure that similar issues are avoided. Thanks, Atlassian Customer Support

We are actively investigating reports of a service disruption affecting Trello users. We'll share updates here as they become available or within the hour.

Our engineering team has implemented a fix, and services have now recovered. We will continue to closely monitor the situation.

On December 12, 2025, from 05:51 UTC to 08:09 UTC, Trello users may have experienced service disruptions on the web page and mobile apps. The issue has now been resolved, and the service is operating normally for all affected customers.

### Summary On December 12, 2025, between 05:31 UTC and 07:11 UTC, Trello customers experienced errors or slow loading times due to a dependency library upgrade that caused high resource usage. The incident was detected within 1 minute by the automated monitoring system and mitigated by rolling back the version of the dependency library which put Atlassian systems into a known good state. The total time to resolution was 1 hour and 41 minutes. ### **IMPACT** The issue caused service disruption for all Trello customers on December 12, 2025 between 05:31 UTC and 07:11 UTC. Users experienced degraded service between 05:31 UTC and 06:32 UTC, and most users were unable to load Trello between 06:32 UTC to 07:07 UTC. ### **ROOT CAUSE** The issue was caused by an upgrade to a dependency library. As a result, there was an increase in system memory consumption causing startups to take longer than expected. When the startup time exceeded the allowed threshold, the worker process was flagged as unresponsive and restarted as an automated recovery action. Because every worker on the instance failed to startup within the expected time, the instance entered a startup loop that required intervention. ### **REMEDIAL ACTIONS PLAN & NEXT STEPS** We know that outages impact your productivity. While we have several testing and preventive processes in place, we didn’t anticipate that the upgrade would consume more memory, which ultimately caused the startup failure loop and service disruption. We are prioritizing the following improvement actions designed to avoid this issue in the future: * Review our automated detection of unresponsive workers and adjust the detection thresholds during initialization. * Improve monitoring during workers startup and restarts due to unresponsiveness. * Enhance the stricter standard process for confirming memory/other data processing resource requirements for planned updates. We apologize to customers whose services were impacted during this incident; we are taking immediate steps to improve the platform’s performance and availability. Thanks, Atlassian Customer Support

### Summary On November 21, 2025, between 13:44 and 15:16 UTC, Trello customers were intermittently unable to view and update data on their boards. Customers also may have experienced issues authenticating with Atlassian products, and creating new GitHub and Slack integrations. The event was triggered by a bug encountered in the software running our edge proxy fleet, which proxies customer traffic to Atlassian cloud services. The changes included the migration of our edge proxy fleet to hosts running an ARM CPU architecture, rather than the AMD64 CPU architecture they had previously been running, which impacted US East customers. The incident was detected within 1 minute by our automated monitoring systems, and mitigated by a scale up of of fleet size, which put Atlassian systems into a known good state. This was followed by a global migration of edge proxy fleet hosts back to AMD64 CPU architecture the following day. ### **IMPACT** During the impact window, US East customers intermittently could not view or update data in Trello. The same underlying issue also impacted our Identity services and integrations with GitHub and Slack, meaning some customers had trouble signing in to Atlassian products or creating new integrations. At the incident’s peak, the incident impacted up to: * 52% of new Trello network connections. * 9% of new GitHub and Slack integrations. * 8% of new Identity network connections. ### **ROOT CAUSE** The issue was caused by a change to CPU architecture from AMD64 to ARM on our edge proxy fleet. This led to a bug that caused these instances to stall under high load, and refuse up to 52% of new connections. As a result, some customers of the products above could not make new connections to Atlassian services, and customers received CloudFront 504 gateway timeout error responses. ### **REMEDIAL ACTIONS PLAN & NEXT STEPS** We know that outages impact your productivity. While we deploy our changes progressively by cloud region to avoid broad impact, on this occasion, our pre-change load testing had not accurately reflected production loads. As part of our response to this incident, and to help prevent recurrence, we rolled back all edge proxy fleets from ARM to AMD64 CPU architecture globally. To minimise the impact of breaking changes to our environments, we plan to implement additional preventative measures such as: * Adding improved load tests into edge proxy fleet deployment pipelines to catch load-related bugs before deployment to production. * Adding alerts to our edge proxy fleet to catch rises in TCP connect times before customer impact. We apologize to customers whose services were impacted during this incident; we are taking steps to help improve the platform’s performance and availability. Thanks, Atlassian Customer Support

### Postmortem publish date: Nov 19th, 2025 ### Summary All dates and times below are in UTC unless stated otherwise. Customers utilizing Atlassian products experienced elevated error rates and degraded performance between Oct 20, 2025 06:48 and Oct 21, 2025 04:05. The service disruptions were triggered due to an [AWS DynamoDB outage](https://aws.amazon.com/message/101925/#:~:text=1%3A50%20PM.-,DynamoDB,-Between%2011%3A48) and further affected by subsequent failures in [AWS EC2](https://aws.amazon.com/message/101925/#:~:text=service%20disruption%20event.-,Amazon%20EC2,-Between%2011%3A48) and [AWS Network Load Balancer](https://aws.amazon.com/message/101925/#:~:text=service%20disruption%20event.-,Amazon%20EC2,-Between%2011%3A48) within the us-east-1 region. The incident started at Oct 20, 2025 06:48 and was detected within six minutes by our automated monitoring systems. Our teams worked to restore all core services by Oct 21, 2025 04:05. Final cleanup of backlogged processes and minor issues was completed on Oct 22, 2025. We recognize the critical role our products play in your daily operations, and we offer our sincere apologies for any impact this incident had on your teams. We are taking immediate steps to enhance the reliability and performance of our services, so that you continue to receive the standard of service you have come to trust. ### IMPACT Before examining product-level impacts, it's helpful to understand Atlassian's service topology and internal dependencies. Products such as Jira and Confluence are deployed across multiple AWS regions. The data for each tenant is stored and processed exclusively within its designated host region. This design is intentional and represents the desired operational state, as it limits the impact of any regional outage strictly to tenants in-region, in this case us-east-1. While in-scope application data is pinned to the region selected by the customer, there are times when systems need to call other internal services that may be based in a different region. If a problem occurs in the main region where these services operate, systems are designed to automatically fail over to a backup region, usually within three minutes. However, if unexpected issues arise during this failover, it can take longer to restore services. In rare cases, this could affect customers in more than one region. It’s important to note that all in-scope application data for supported products is pinned according to a customer’s chosen region. **Jira** Between Oct 20, 2025 06:48 and Oct 20, 2025 20:00, customers with tenants hosted in the us-east-1 region experienced increased error rates when accessing core entities such as Issues, Boards, and Backlogs. This disruption was caused by AWS's inability to allocate AWS EC2 instances and elevated errors in AWS Network Load Balancer \(NLB\). During this window, users may also have observed intermittent timeouts, slow page loads, and failures when performing operations like creating or updating issues, loading board views, and executing workflow transitions. Between Oct 20, 2025 08:36 and Oct 20, 2025 09:23, customers across all regions experienced elevated failure rates when attempting to load Jira pages. This disruption was caused by the regional frontend service entering an unhealthy state during this specific time interval. Normally, the frontend service connects to the primary AWS DynamoDB instance located in the us-east-1 to retrieve the most recent configuration data necessary for proper operation. Additionally, the service is designed with a fallback mechanism that references static configuration data in the event that the primary database becomes inaccessible. Unfortunately, a latent bug existed in the local fallback path. When the frontend service nodes restarted, they were unable to load critical operational configuration data from primary or fallback sources, leading to the observed failures experienced by customers. Between Oct 20, 2025 06:48 and Oct 21, 2025 06:30, customers experienced significant delays and missing Jira in-app notifications across all regions. The notification ingestion service, which is hosted exclusively in us-east-1, exhibited an increased failure rate when processing notification messages due to AWS EC2 and NLB issues. This issue resulted in notifications being delayed - and in some cases, not delivered at all - to users worldwide. **Jira Service Management \(JSM\)** JSM was impacted similarly to Jira above, with the same timeframes and for the same reasons. Between Oct 20, 2025 08:36 and Oct 20, 2025 09:23, customers across all regions experienced significantly elevated failure rates when attempting to load JSM pages. This affected all JSM experiences including the Help Centre, Portal, Queues, Work Items, Operations, and Alerts. **Confluence** Between Oct 20, 2025 06:48 and Oct 21, 2025 02:45, customers using Confluence in the us-east-1 region experienced elevated failure rates when performing common operations such as editing pages or adding comments. The primary cause of this service degradation was the system's inability to auto-scale due to AWS EC2 issues to manage peak traffic load effectively. Though the AWS outage ended at Oct 20, 21:09, a subset of customers continued to experience failures as some Confluence web server nodes across multiple clusters remained in an unhealthy state. This was ultimately mitigated by recycling the affected nodes. To protect our systems while AWS recovered, we made a deliberate decision to enable node termination protection. This action successfully preserved our server capacity but, as a trade-off, it extended the time required for a full recovery once AWS services were restored. **Automation** Between Oct 20, 2025 06:55 and Oct 20, 2025 23:59, automation customers whose rules are processed in us-east-1 experienced delays of up to 23 hours in rule execution. During this window, some events triggering rule executions were processed out of order because they arrived later during backlog processing. This caused potential inconsistencies in workflow executions, as rules were run in the order events were received, not when the action causing the event occurred. Additionally, some rule actions failed because they depend on first-party and third-party systems, which were also affected by the AWS outage. Customers can see most of these failures in their audit logs; however, a few updates were not logged due to the nature of the outage. By Oct 21, 2025 5:30, the backlog of rule runs in us-east-1 was cleared. Although most of these delayed rules were successfully handled, there were some additional replays of events to ensure completeness. Our investigation confirmed that a few events may never have triggered their associated rules due to the outage. Between Oct 20, 2025 06:55 and Oct 20, 2025 11:20, all non-us-east-1 regional automation services experienced delays of up to 4 hours in rule execution. This was caused by an upstream service that was unable to deliver events as expected. The delivery service encountered a failure due to a cross-region dependency call to a service hosted in the us-east-1 region. Because of this dependency issue, the delivery service was unable to successfully deliver events throughout this time frame, resulting in customer-defined rules not being executed in a timely manner. **Bitbucket and Pipelines** Between Oct 20, 2025 06:48 and Oct 20, 2025 09:33, Bitbucket experienced intermittent unavailability across core services. During this period, users faced increased error rates and latency when signing in, navigating repositories, and performing essential actions such as creating, updating, or approving pull requests. The primary cause was an AWS DynamoDB outage that impacted downstream services. Between Oct 20, 2025 06:48 and Oct 20, 2025 22:46, numerous Bitbucket Pipeline steps failed to start, stalled mid-execution, or experienced significant queueing delays. Impact varied, with partial recoveries followed by degradation as downstream components re-synchronized. The primary cause was an AWS DynamoDB outage, compounded by instability in AWS EC2 instance availability and AWS Network Load Balancers. Furthermore, Bitbucket Pipelines continued to experience a low but persistent rate of step timeouts and scheduling errors due to AWS bare-metal capacity shortages in select availability zones. Atlassian coordinated with AWS to provision additional bare-metal hosts and addressed a significant backlog of pending pods, successfully restoring services by 01:30 on Oct 21, 2025. **Trello** Between Oct 20, 2025 06:48 and Oct 20, 2025 15:25, users of Trello experienced widespread service degradation and intermittent failures due to upstream AWS issues affecting multiple components, including AWS DynamoDB and subsequent AWS EC2 capacity constraints. During this period, customers reported elevated error rates when loading boards, opening cards, adding comments or attachments. **Login** Between Oct 20, 2025 06:48 and Oct 20, 2025 09:30, a small subset of users experienced failures when attempting to initiate new login sessions using SAML tokens. This resulted in an inability for those users to access Atlassian products during that time period. However, users who already had valid active sessions were not affected by this issue and continued to have uninterrupted access. The issue impacted all regions globally because regional identity services relied on a write replica located in the us-east-1 region to synchronize profile data. When the primary region became unavailable, the failover to a secondary database in another region failed, which delayed recovery. This failover defect has since been addressed. **Statuspage** Between Oct 20, 2025 06:48 and Oct 20, 2025 09:30, Statuspage customers who were not already logged in to the management portal were unable to log in to create or update incident statuses. This impact was restricted only to users who were not already logged in at the time. The root cause was the same as described in the Login section above, and it was resolved by the same remediation steps. ### REMEDIAL ACTION PLAN & NEXT STEPS We have completed the following critical actions designed to help prevent cross-region impact from similar issues: * Resolved the code defect in the fallback option to ensure that Jira Frontend Services in other regions remain unaffected during a region-wide outage. * Fixed the issue that prevented timely failover of the identity service which impacted new login sessions. * Resolved the code defect so that delivery services in unaffected regions remain operational during region-wide outages. Additionally, we are prioritizing the following improvement actions: * Implement mitigation strategies to strengthen resilience against region-wide outages in the notification ingestion service. Although disruptions to our cloud services are sometimes unavoidable during outages of the underlying cloud provider, we continuously evaluate and improve test coverage to strengthen resilience of our cloud services against these issues. We recognize the critical importance of our products to your daily operations and overall productivity, and we extend our sincere apologies for any disruptions this incident may have caused your teams. If you were impacted and require additional details for internal post-incident reviews, please reach out to your Atlassian support representative with affected timeframes and tenant identifiers so we can correlate logs and provide guidance.

### **SUMMARY** On May 15, 2025, between 13:55 and 14:18 UTC, Atlassian customers using the Trello product experienced errors or slow loading times when attempting to view their cards and boards. The event was triggered by a database plan cache expiring and high resource usage caused by subsequent database query planning operations. The particular database shard that was impacted held data that was required for every card load. The incident was detected within two minutes by the automated monitoring system and mitigated by increasing resources available to the affected database shard, which put Atlassian systems into a known good state. The total time to resolution was about 23 minutes. ### **IMPACT** The overall impact was between May 15, 2025, 13:55 and May 15, 2025, 14:18 UTC on the Trello product. The incident caused service disruption for all Trello customers. ### **ROOT CAUSE** The issue was caused by a query plan expiring from the database cache, which caused incoming queries to go through a replanning operation. These queries had multiple plans that could satisfy them, and depending on the size of the query, one plan might be significantly more efficient than another. This caused the query planner to perform a great many more replanning operations than usual, which consumed all of the CPU on the server for a brief moment. Once the CPU was consumed, the planning operations themselves began taking too long and therefore required constant replanning in an effort to find more efficient options. This negative feedback loop could not be broken without intervention. ### **REMEDIAL ACTIONS PLAN & NEXT STEPS** We know that outages impact your productivity. While we have a number of testing and preventative processes in place, this specific issue wasn’t identified because it would only occur under very distinct conditions, including the amount of load and the order of database queries. We are prioritizing the following improvement actions to avoid repeating this type of incident: * Review our capacity planning thresholds and ensure that all shards have sufficient overhead to handle unexpected load. * Improve query planner performance by: * Implement hinting for known problematic query shapes to circumvent the query planner. * Investigate long-term generalized solutions to prevent query planner thrashing. Furthermore, we are prioritizing the following additional measures to reduce the impact of any future incidents: * Analyze and reduce single points of failure for loading Trello boards and cards. We apologize to customers whose services were impacted during this incident; we are taking immediate steps to improve the platform’s performance and availability. Thanks, Atlassian Customer Support
