Some Copilot Cloud Agent jobs not starting
Incident
Report for GitHub
Resolved
On August 5, 2026, between 11:02 and 11:54 UTC, the GitHub Copilot cloud agent service was degraded and new cloud agent jobs were delayed from starting. During this period 100% of newly submitted agent jobs were affected. The incident was limited to delay of cloud agent jobs. No jobs were lost and the queued backlog was processed by 13:00 UTC. This was due to an internal rate limit used to protect service availability that was enabled more broadly than intended delaying more traffic than expected.
The service recovered when the rate limit window expired. We then tuned the control so it no longer affected unrelated coding agent traffic.
We are working to improve the control's scoping and our monitoring and alerting to reduce our time to detection and mitigation of similar issues in the future.
