  1. resolved

    Starting at 07:57 UTC on September 23, GitHub experienced elevated 500 and 404 responses across several application pages. This caused failures when installing GitHub Apps, creating organizations, and making some organization membership changes. Customers also experienced delayed label updates and stale search results in Projects. <br /><br />The infrastructure failure was isolated to our Azure Central US region. The API errors were mitigated by 10:58 UTC on September 23. Projects' processing continued to recover while an accumulated backlog was drained, and full service was restored at 04:55 UTC on September 24. <br /><br />The incident was caused by a failed planned maintenance operation on a primary database. Automated recovery initiated an emergency database failover, after which several replicas in the affected region were unable to resume replication correctly. This reduced available database capacity and caused the API errors and downstream Projects processing delays. <br /><br />We have mitigated the immediate failure mode. We are also improving maintenance safety checks, database failover handling, post-failover replica validation, and downstream processing resilience to reduce the likelihood and impact of similar incidents.

  5. investigating

    We've deployed a change intended to accelerate processing of the backlog of issue label updates in Projects. A sizable backlog still remains and we continue working through it. All other services are operating normally. We will provide another update within the next hour.

  8. investigating

    Continuing to investigate the lag that may be experienced in issue labels being accurately reflected in Projects. We are working on alternate solutions to process the backlog of label updates.

  9. investigating

    We will post another update in approximately one hour to share our progress.

    保存リビジョンでの確認:06 Oct 2026, 13:58:39 UTC
  10. investigating

    Updates to issue labels may be delayed in being reflected in Projects by about ~10 minutes. We have added some capacity to work through the backlog more quickly, but it'll likely be a few hours to complete processing the full backlog of messages. All other services are available.
