Incident with Actions - Larger hosted runners
Final update
On October 23, 2025, between 15:54 UTC and 19:20 UTC, GitHub Actions larger hosted runners experienced degraded performance, with 1.4% of overall workflow runs and 29% of larger hosted runner jobs failing to start or timing out within 5 minutes. The full set of contributing factors is still under investigation, but the customer impact was due to database performance degradation, triggered by routine database changes causing a load profile that triggered a bug in the underlying database platform used for larger runners. Impact was mitigated through a combination of scaling up the database and reducing load. We are working with partners to resolve the underlying bug and have paused similar database changes until it is resolved.
