GitHub: Incident with Copilot
Timeline of updates
- resolved
On April 1, 2026, between 07:29 and 12:41 UTC, some customers experienced elevated 5xx errors and increased latency when using GitHub Copilot features that rely on
/agents/sessionsendpoints (including creating or viewing agent sessions). The issue was caused by resource exhaustion in one of the Copilot backend services handling these requests, in turn, causing timeouts and failed requests. We mitigated the incident by increasing the service’s available compute resources and tuning its runtime concurrency settings. Service health returned to normal and the incident was fully resolved by 12:41 UTC.
