Status: Resolved

Update: We have identified and resolved a problem with Forge hosted storage, where some paginated queries kept repeating the last page. The incident was detected by our internal monitoring and was resolved quickly after detection by reverting the deployment. Activating changes recently made to the query cursors for paginated queries introduced a bug that impacted some apps. A small number of requests were impacted over a 16-minute window, while the incident lasted. Timeline: - 25/Mar/24 10:08 p.m. UTC - Impact started, when the changes were deployed to production - 25/Mar/24 10:09 p.m. UTC - Incident was detected - 25/Mar/24 10:24 p.m. UTC - Incident was resolved and impact ended The impact of this incident has been completely mitigated and our monitoring tools confirm that query operations are back to the pre-incident behaviour. We have also resolved the underlying bug and deployed the fix to production, completely eliminating the cause of this incident. We apologise for any inconvenience this may have caused to our customers and our developer community.

Status: Postmortem

Update: ### **Summary** On February 14, 2024, between 20:05 UTC and 23:03 UTC, Atlassian customers on the following cloud products encountered a service disruption: Access, Atlas, Atlassian Analytics, Bitbucket, Compass, Confluence, Ecosystem apps, Jira Service Management, Jira Software, Jira Work Management, Jira Product Discovery, Opsgenie, StatusPage, and Trello. As part of a security and compliance uplift, we had scheduled the deletion of unused and legacy domain names used for internal service-to-service connections. Active domain names were incorrectly deleted during this event. This impacted all cloud customers across all regions. The issue was identified and resolved through the rollback of the faulty deployment to restore the domain names and Atlassian systems to a stable state. The time to resolution was two hours and 58 minutes. ### **IMPACT** External customers started reporting issues with Atlassian cloud products at 20:52 UTC. The impact of the failed change led to performance degradation or in some cases, complete service disruption. Symptoms experienced by end-users were unsuccessful page loads and/or failed interactions with our cloud products. ### **ROOT CAUSE** As part of a security and compliance uplift, we had scheduled the deletion of unused and legacy domain names that were being used for internal service-to-service connections. Active domain names were incorrectly deleted during this operation. ### **REMEDIAL ACTIONS PLAN & NEXT STEPS** We know that outages impact your productivity. The detection was delayed because existing testing & monitoring focused on service health rather than the entire system’s availability. To prevent a recurrence of this type of incident, we are implementing the following improvement measures: * Canary checks to monitor the entire system availability. * Faster rollback procedures for this type of service impact. * Stricter change control procedures for infrastructure modifications. * Migration of all DNS records to centralised management and stricter access controls on modification to DNS records. 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
