**What happened?**  On October 19, 2026, xMatters internal monitoring tools detected service degradation at 10:03 PM Pacific. Shortly after, some customers reported experiencing problems accessing xMatters or using integration and notification services.  **Why did it happen?**  Google Cloud experienced an outage affecting its EU-West-2 region. This disrupted xMatters services in the affected region.  **How did we respond?**  xMatters Support, Engineering, and Operations teams initiated the Major Incident Management process and mitigated the impact of the outage by failing affected systems over to another region. Services became available as systems transitioned. xMatters remained in Monitoring and verified service stability while Google continued recovery work in its affected region.  **What are we doing to prevent it from happening again?**  xMatters is designed with regional resiliency to mitigate the impact of infrastructure provider outages. During this incident, those resiliency measures operated as intended and enabled affected services to be transitioned to another region. Engineering and Operations are reviewing the incident resolution response to identify opportunities to further streamline recovery procedures and reduce recovery time during similar events.

**What happened?**  On October 1, 2026, xMatters monitoring first detected service degradation at 9:27 AM Pacific, and the first customer report was received at 10:03 AM. Customers in US-EAST1 experienced intermittent Web Interface access issues, API timeouts, and delays or failures when integrations initiated alerts and notifications. Some customers in US-CENTRAL1 may also have experienced voice notification issues during the same period.  **Why did it happen?**  During automated infrastructure scaling in US-EAST1, multiple application services became concentrated on the same compute resource. That resource reached its processing capacity, reducing the capacity available to serve customer requests. Service degradation continued across dependent xMatters functions while additional processing capacity was being added.  **How did we respond?**  As soon as the first customer reported an issue, xMatters Customer Support initiated the internal Major Incident Management process and engaged the Engineering and Operations teams. The incident response team increased service capacity, monitored the affected services, and verified recovery across the Web Interface, APIs, integrations, and notification processing. Service began stabilizing by 10:37 AM, and primary customer impact ended at 10:46 AM. The team continued monitoring before resolving the public incident at 11:56 AM.  **What are we doing to prevent it from happening again?**  Engineering is reviewing service capacity and workload distribution controls to reduce the risk of multiple critical services competing for the same compute resources. The team is also reviewing service health checks and alerting so that capacity issues are identified earlier to ensure required capacity is always available.

xMatters has identified an issue with xMatters SMS Notification for some clients in All Regions to numbers in the United States and Canada from our short code 87961. We have failed over to our secondary short code 66936. We are currently investigating the issue and will update as information becomes available. If you are also experiencing issues, or if you're not sure whether this issue impacts your service, please contact xMatters Client Assistance at https://support.xmatters.com/hc/en-us/requests/new - our support agents are waiting to help.

All SMS traffic to the US and Canada is now being delivered through our secondary short code 66936. We are currently monitoring the situation to ensure the implementation is stable and that all services are restored.

The short code issue has been addressed, and all SMS notifications to Canada and the United States are now being delivered from our 87961 short code. Thank you for your patience while we addressed this matter.

**What happened?** On September 21st, 2026, customers reported an issue to xMatters Client Assistance where SMS messages were failing to send to end users in North America. **Why did it happen?** The SMS delivery failures occurred because the short code used to send SMS messages became unavailable. The system should have automatically routed failed messages through the secondary messaging provider. However, the specific error returned for these failures did not trigger the configured failover process, causing disrupted SMS delivery to end users in the US and Canada. **How did we respond?** Once Engineering identified the SMS delivery issue, they initiated the Major Incident Management process and began removing the affected short code from the messaging configuration. During this process, Engineering encountered additional issues that prevented the system from automatically switching SMS traffic to the secondary messaging provider. Engineering manually intervened to complete the switch to the secondary provider and restore SMS delivery. After service recovered, Engineering monitored the system to confirm that SMS delivery was operating normally. **What are we doing to prevent it from happening again?** Engineering routed SMS traffic through the secondary messaging provider while they worked to restore the previous primary short code. Engineering is also addressing the failover behavior that prevented the system from automatically switching providers when this specific error occurred. These improvements to the process will reduce the risk of a similar short code issue disrupting SMS delivery in the future.

**What happened?**  On July 1st, 2026, some customers reported an issue to xMatters Customer Support where they were encountering authentication errors when accessing the web user interface.  **Why did it happen?**  This issue occurred because a database cluster reached 100% resource utilization, causing database requests to time out. An exceptional traffic pattern exposed a set of slow-running queries, which significantly increased query latency on the cluster. As latency increased, there was resource starvation and further degradation of the cluster's responsiveness, resulting in timeouts.  **How did we respond?**  As soon as Customer Support confirmed the issue, they engaged the Engineering teams to investigate. As designed, the system had restored itself before Engineering could implement any mitigation or recovery actions, but the teams were still able to identify and isolate the root cause.  **What are we doing to prevent it from happening again?**  To prevent this issue from reoccurring, the Engineering Team designed, developed, and tested a fix. They deployed the fix in the morning of Wednesday, July 8th, 2026, and it has been successfully implemented for all instances.

xMatters have identified a potential issue with the xMatters Web User Interface for some clients located in the Europe region. Accessing some pages including Alert details produces an error.

**What happened?**  On May 1st, 2026, some customers reported an issue to xMatters Customer Support where attempting to send a message via the web user interface or viewing an alert on the Alerts report resulted in an error being displayed. The issue only affected the Reporting functions in the EMEA region; the system continued to accept signals, generate alerts, and send notifications across all regions.  **Why did it happen?**  The issue occurred when, during routine database maintenance, the database called a mismatched version of the library, resulting in an internal database error. The version mismatch within the cluster was traced to a prior database engine upgrade where a subset of replica nodes did not restart into the upgraded version. At no point was there any risk to data integrity.  **How did we respond?**  As soon as Customer Support confirmed the issue, they engaged the Engineering teams, who were able to identify the root cause and restore version consistency across all nodes. The teams validated stability and confirmed that all services were restored.  **What are we doing to prevent it from happening again?**  The Engineering Team has added explicit post-upgrade verification checks and monitoring to ensure node alignment is confirmed and maintained. This will provide safeguards to ensure node version alignment after upgrades and prevent this issue from reoccurring.

**What happened?**  On April 1st, 2026, some customers reported an issue to xMatters Customer Support where the Alerts or Notifications reports were timing out and failing to load.  **Why did it happen?**  This issue occurred because a backend service was experiencing significant unexpected load that caused report processing to be delayed. The ongoing resource constraint resulted in timeouts.  **How did we respond?**  As soon as customers reported an issue, Customer Support launched an investigation and escalated to the Engineering teams. The teams initiated rolling restart procedures for the applicable backend services to restore functionality. Once the rolling restart was completed, service was fully restored.  **What are we doing to prevent it from happening again?**  The Engineering teams are currently working to identify any possible bottlenecks that may have caused performance issues. In the interim, they have increased and adjusted resource allocation for several services to handle potential processing delays and prevent potential recurrences.

We have reports that some users are not able to login to xMatters using SSO to login to the xMatters Web User Interface in All Regions.

**What happened?**  On March 10th, 2026, some customers reported an issue to xMatters Customer Support where they were encountering a 404 error page when attempting to log in to their instances via SSO. Some users may also have encountered a “We’ve run into a problem while retrieving your data.” error message.  **Why did it happen?**  This issue occurred during a routine maintenance update to the xMatters platform. Although several components of the platform were updated, specific configurations of the component related to SSO-based authentication conflicted with the update and resulted in 404 errors. This issue was limited to those few customers that had specific criteria set for their SSO configuration.  **How did we respond?**  As soon as customers reported the issue, Customer Support verified the issue and escalated immediately to Engineering. The team traced the issue to the maintenance deployment and initiated rollback procedures to restore functionality. Once the rollback was completed, the 404 errors ceased and service was confirmed restored.  **What are we doing to prevent it from happening again?**  The Engineering teams have implemented additional testing for any configuration criteria related to the SSO-based authentication component. In addition, they have begun working on an improved maintenance plan to prevent further issues that could occur during similar deployments.

xMatters monitoring tools have identified a potential issue with xMatters On-Demand for some clients located in the North America region.

**What happened?** On November 21, 2025, at 12:50 PM UTC, the xMatters internal monitoring tools detected irregular behavior in how internal traffic was being routed. Some customers in the APAC region communicating with services in North America \(specifically US-East\) may have encountered intermittent request failures or increased latency. Only traffic between these two regions was affected; all other systems and regions continued normal operations. **Why did it happen?** A temporary network disruption between Australia Southeast and US-East caused one internal routing node in Australia to lose accurate information about available backend systems in USEast. The node generated an incomplete routing configuration and temporarily stopped directing traffic to US-East. Under normal circumstances, routing updates refresh automatically when connectivity returns. In this case, the affected node did not recover cleanly and remained in a stale state until Engineering intervened. **How did we respond?** As soon as Engineering was alerted through internal monitoring, they engaged with the platform engineering team, service owners and Customer Support to launch an investigation. The teams reached out to impacted customers to validate issue symptoms and restarted routing components in both affected regions to force a configuration refresh. Once the restart completed, routing returned to normal levels while the teams continued to monitor and investigate the root cause. They were able to confirm that only one routing node and specific cross-region traffic was impacted. **What are we doing to prevent it from happening again?** While teams were mitigating this issue, they created new alerting rules to detect the routing patterns they observed during the incident and expanded internal monitoring to help identify when routing nodes fail to refresh their configuration or otherwise enter a ‘stale’ state. The teams also have planned and prepared infrastructure updates that will further reduce the risk of similar issues. These include improved configuration recovery behavior, enhanced stability for routing components, and additional logging and observability improvements for diagnosing routing anomalies. They will deploy these updates once the current code freeze window has elapsed.

xMatters monitoring tools have identified a issue with xMatters Conferencing and Voice calls for clients in All Regions. The issue is due to downstream provider outages.

Our downstream providers have deployed a fix and testing shows conferencing and voice systems are now working as expected. We are currently monitoring the situation to ensure the implementation is stable and that all services are restored.

Our provider has confirmed the issue has been addressed, and all services have been restored. Thank you for your patience while we addressed this matter.

**What happened?**  On October 20th, 2025, at approximately 1:21 AM Pacific, customers began reporting an issue affecting live call routing, conferences, and voice notifications. During this issue, customers in all regions would have been affected. **Why did it happen?**  This issue was caused by a global AWS outage that impacted one of our downstream providers, resulting in voice notifications, live call routing, and conferencing they were handling to fail.  **How did we respond?**  As soon as the first customer reported an issue, Customer Support engaged the Engineering teams and launched an investigation. Once they identified the root cause, the teams updated the primary provider for affected regions to an alternate provider that was not affected by the AWS outage. When the new provider was assigned, customers reported that all services were operating correctly.  **What are we doing to prevent it from happening again?**  While this issue was out of our control or that of our provider, we are working to identify potential ways to improve resilience in case of external factors such as this.

The xMatters monitoring tools have alerted Customer Support to a potential issue with the integration platform in the North America region. Our technical teams have identified intermittent request failures and occasional slowdowns, though the service appears to be responsive and recovering correctly. We are continuing to monitor the situation and mitigating where possible, though some users may encounter a 5xx response code when submitting a request.

The issue has been addressed, and all services are running as expected. Thank you for your patience while we addressed this matter.

**What happened?**  On October 10th, 2025, at approximately 4:14 PM Pacific, the xMatters internal monitoring tools alerted Customer Support to service degradation related to an issue that was already being internally monitored with the Integration Platform in the North American region. While this issue was being investigated and mitigated, customers may have experienced intermittent request failures and occasional slowdowns.  **Why did it happen?**  These particular issues were caused by a security update that caused conflicts with the underlying runtime environment, specifically the memory management routine. Slow performance of the routine was triggering frequent health checks for a request processing service and causing automatic restarts.  **How did we respond?**  As soon as the internal monitoring tools alerted Engineering to a potential issue, they began performing manual rolling restarts and deployed more forgiving liveness checks to avoid increasing error rates and to minimize any potential impact to customers. They also increased resources for the impacted service to improve responsiveness of the underlying routine and deployed a configuration fix to the Http Client Cache to try and stabilize the system. While mitigating the potential impact, they also increased monitoring levels as they continued to investigate the root cause and were able to deploy an update to the service and environment configuration on October 13 that resolved the issue. They continued monitoring and confirmed that the system was stable and all services were operational.  **What are we doing to prevent it from happening again?**  Engineering has updated the backend service and deployed additional updates and monitoring to the system configuration that will improve overall stability for the environment and prevent this issue from reoccurring.

**What happened?**  On September 23rd, 2025, at approximately 8:31 PM Pacific, the xMatters internal monitoring tools alerted the xMatters Support Team to an issue with Apple iOS notifications. Users were not receiving notifications on Apple iOS devices; other device types and alert and response processing were not impacted and continued to operate without interruption.  **Why did it happen?**  The issue occurred because of a backend service patch applied by the Engineering teams that affected necessary dependencies for Apple Push notification delivery.  **How did we respond?**  As soon as the monitoring tools alerted the Support team, they engaged the Engineering teams to launch an investigation. The teams quickly identified the source of the issue as a recent backend service patch and initiated a rollback of the patch. Once the rollback was complete, the teams confirmed that all services had been restored.  **What are we doing to prevent it from happening again?**  The Engineering team is working to enhance testing of future patches and improving visibility into the health of services. This will help to proactively resolve issues or, when necessary, initiate rollbacks more quickly without impacting customers.

### What happened? On August 5th, 2025, at approximately 7:53 PM Pacific, the xMatters internal monitoring tools alerted the xMatters Support team to an issue in the North America region with notification delivery. Some xMatters customers may have experienced delays when receiving notifications or noticed failed alerts in the system. ### Why did it happen? The issue occurred because of a network problem that disrupted communication between parts of the queuing system. This caused some components to become temporarily out of sync, leading to timeouts, internal connectivity failures, and a small number of messages not being processed during the disruption. As the system recovered, some performance was degraded until normal operation could be restored. ### How did we respond? As soon as the xMatters monitoring tools reported an issue, the xMatters Support Team initiated the internal Major Incident Management process and engaged the Engineering and incident response teams. The teams quickly mitigated the issue and restored performance by redirecting traffic from our message queuing system in the affected region \(us-central\) to our message queuing system in another local region \(us-east\). After the issue was resolved, the teams directed traffic back to the restored region. ### What are we doing to prevent it from happening again? The Engineering team has determined that the best approach to prevent this issue from reoccurring is to replace the current message queuing system. Work on the replacement system is well underway and the teams will retire the current system as soon as they have finished the replacement.

**What happened?**  On May 13, 2025 at approximately 10:45 AM Pacific, xMatters internal monitoring tools identified an issue where customers in the EU region experienced intermittent web UI and API timeouts.  **Why did it happen?**  The issue occurred because a backend queueing service experienced network timeouts during an unpredictable rapid increase in usage. The increase in resource consumption due to the surge in network usage caused service timeouts and restarts, as well as higher latency which caused further delays in responses to backend requests.  **How did we respond?**  xMatters internal monitoring tools alerted the xMatters Incident Response Team to the issue, then the team launched the internal SEV-1 process. Due to early detection, Engineering teams were able to scale up the queueing services to prevent further service degradation and availability issues. The network timeouts were resolved after resources were scaled up to accommodate the increase in usage.  **What are we doing to prevent it from happening again?**  The Engineering teams have adjusted resources to better compensate for sudden usage increases and to prevent them from affecting backend services. The improvement in resource allocation and adaptability should prevent similar issues from occurring in the future.

**What happened?** On April 3, 2025, at approximately 9:32 AM Pacific, the xMatters internal monitoring systems identified an issue where the system was not processing events initiated via Flow Designer across multiple regions. Customers may have observed the system not processing events or creating alerts while the issue was in progress. **Why did it happen?** The issue occurred when a routine update to add new permissions to the xMatters' Google Cloud Platform \(GCP\) unexpectedly removed required permissions. When the teams performed the update, which should not have had any impact to customers, the policy used in the automation script was the authoritative resource at the GCP project level rather than authoritative at the individual resource level. Although the teams tested the change before deploying it and found no changes beyond what was included in the update, when the update was deployed to production GCP removed all permissions that were not in the policy in the background. Because the policy only included the new permissions, all other permissions were removed. **How did we respond?** As soon as the xMatters monitoring tools reported an issue with the system not processing events, the incident response teams initiated the internal Major Incident Management process and engaged the Engineering and Support teams. The teams were able to quickly identify the recent update as the root cause of the issue and reverted the change to restore the permissions that were managed by the automation process. This restored access and functionality for most of the xMatters services, but restoring permissions for Flow Designer proved to be more complicated. The teams determined that missing permissions for the xMatters infrastructure were Google-generated permissions essential for specific xMatters services and engaged GCP Support to aid in the investigation. The teams generated a list of all permissions that existed prior to the update and designed a fix to re-apply them to the development environment. Once the teams had implemented the change and validated that the missing permissions and all services had been restored in the development environment, they moved to quickly apply the fix across all staging and production environments. Monitoring tools and customers confirmed that services were fully functional, and the teams continued to monitor the system as it processed all messages queued by the Flow Designer services. The system was fully restored at 2:46 PM Pacific. **What are we doing to prevent it from happening again?** The Engineering teams were able to identify all of the permissions created in the xMatters environment, including those that are created by Google, and are ensuring they are added to the management scripts. The teams are adding additional rigor to the application of these types of infrastructure changes to run idempotence tests after the changes are applied to ensure that there are no changes pending. Should a change be applied that fails this test, it will cause failures in development environments, which would catch and prevent a similar issue from occurring.

This incident has been resolved.

**What happened?** On July 5th, at approximately 8:35AM Pacific, the xMatters monitoring tools alerted Customer Support to an issue where alert notifications were not being sent out for some customers in the North America region. Some customers attempting to initiate alerts may have encountered long delays in processing or may have had requests time out. **Why did it happen?** This issue occurred due to a sudden spike in the number of resources required by our backend services. The resulting memory overload issue caused some request handlers to time out before they could properly process incoming alerts. **How did we respond?** As soon as the xMatters Customer Support team confirmed the issue from the monitoring tools, they initiate the internal major incident management process and engaged the xMatters Engineering teams. To immediately mitigate the issue and restore service quickly, the incident response teams performed a rolling restart for the affected services. As soon as the restart was completed, the system resumed processing alerts and all services were restored. **What are we doing to prevent it from happening again?** The Engineering teams have implemented a performance enhancement for backend service queries. In addition, the teams are evaluating and testing additional methods to help mitigate resource spikes and prevent them from impacting alert notifications in the future. Once development and testing are complete, we'll deploy these changes with our regularly scheduled maintenance. **Timeline:** July 5th, 2024 8:35AM PT - xMatters internal monitoring tools alert to potential issue. 9:22AM PT - Issue identified. 9:36AM PT - Rolling restart initiated. 10:16AM PT - Issue Resolved.
