  4. resolved

    On April 24, 2026, from approximately 11:39 UTC to April 25, 2026 at 00:15 UTC, GitHub Actions experienced delays and timeouts for Larger Hosted Runner jobs using VNet injection in the East US region without a failover region configured. Standard and Self-hosted runners were not impacted. This was caused by backend failures in our compute provider’s provisioning, scaling, and update operations for VMs in the East US region and mitigated by a rollback across all affected Availability Zones. More detail is available at https://azure.status.microsoft/en-us/status/history/?trackingId=5GP8-W0G. We are working to improve the reliability of our annotations for jobs impacted by regional issues and are adding system log notifications as an additional customer communication channel alongside annotations. VNet Failover is also now in public preview, allowing customers to evacuate Larger Hosted Runners using VNet injection in cases like this.
