    On April 28, 2026, from approximately 12:41 UTC to 17:09 UTC, GitHub Actions jobs using Standard Ubuntu 22 and Ubuntu 24 hosted runners experienced run start delays. Approximately 8% of hosted runner jobs using Ubuntu 22 and Ubuntu 24 experienced delays greater than 5 minutes or failures. Larger and self-hosted runners were not impacted. This was caused by a performance regression introduced in the VM reimage process. That reimage delay lowered the overall capacity of runners available to pick up new jobs. This was mitigated with a rollback to a known good image version. We are addressing the core issue with reimage performance and improving the granularity of reimage telemetry across our services and our compute provider to more quickly diagnose similar issues in the future. Finally, we are evaluating other rollout changes to automatically detect similar regressions.
