Incident Report

Summary AI Generated

GitHub Actions experienced degraded availability for approximately 2.8 hours due to a database primary failure affecting inbound job queues. A failover to a replica was initiated but did not fully resolve the issue, requiring traffic throttling while upstream Vitess database problems were addressed; GitHub Pages was briefly impacted before returning to normal. Once traffic was gradually ramped back up and queues cleared, the incident was resolved, with a root cause analysis to follow.

We are continuing to observe recovery and expect actions inbound queues to be back to normal in <30min. Work will continue to flow through the system subject to per-customer concurrency limits.

We are continuing to observe recovery and delayed queues are burning down. Some customers will continue to see increased delays until all throttled work has been completed - we expect this within the next hour.
