On October 6, 2025, between 8:05 UTC and 09:00 UTC, for our GitHub Enterprise Cloud - EU installation, our job queueing service was degraded for 55m, resulting in delays to Actions workflow runs, jobs, and related checks. This impacted 100% of workflow runs and jobs that were queued during that period of time. The customer impact was an inability to merge PRs on repositories with branch protections. This was caused by an intermittent networking issue which our job queueing service did not gracefully recover from.
This incident was resolved by a manual redeploy of the job queueing service.
To reduce our time to detection, we have repaired the monitor that should have caught this error earlier. Additionally, we are investing in self-healing mechanisms to prevent similar failure modes in the future.

Update
Actions is now in full recovery and delayed workflow runs and job updates are being processed again. We will continue to monitor and provide a full report once root cause analysis is complete.
