Approximately 30% of GitHub Actions runs on GitHub-hosted runners are experiencing run start delays exceeding 5 minutes. A smaller percentage of those are exhausting retries and failing to start. This has caused some customers to exceed their hosted compute concurrency and experience increased impact. We are continuing to working on infrastructure mitigations. Next update in one hour.

We're seeing Actions and Pages recovery. For a period of approximate 20 minutes ~96% of GitHub Actions runs on GitHub-hosted runners were failing to start, but has now recovered and we are seeing jobs processing. GitHub pages builds were also failing during that period, but Pages are still accessible. We are continuing to monitor for full recovery.

Actions is experiencing degraded availability. We are continuing to investigate.
- investigating Jul 09, 2026, 01:17 PM UTC
We are continuing to monitor slow recovery in Actions and Pages builds as the system works through the high volume of backlog. Customers may see a small rate of API and job failures as the system is recovering. Copilot Cloud Agent and Copilot Code Review also failed to start for approximately 30 minutes during this incident, and we are monitoring recovery. Pages were accessible throughout the incident.
