EU - Incident with Actions

Between January 31, 2025 19:08 UTC and Feb 1, 2025 16:33 UTC, GitHub-hosted runners for Actions experienced a disruption on GitHub Enterprise Cloud in EU and Australia regions. 100% of Actions jobs in these regions using hosted runners failed with an error indicating an internal failure when running the job.

The issue was caused by an unexpected removal of critical DNS records caused by the interaction of two unrelated configuration changes. Each change was validated during deployment, but the hosted runner impact started after deployment validation was completed. A gap in alerting led to a significant delay in detecting the impact and initiating mitigation.

We have completed monitoring improvements for earlier detection, updated the guidance on DNS changes, and are working on improvements to harden the deployment and validation of similar changes for the future.

We have found and mitigated the issue, actions should now be working again.

We're continuing to investigate the cause of the issue with Actions

We have detected an issue where users are unable to run actions using GitHub hosted runners.

We are investigating reports of degraded performance for Actions
