- resolved
On May 28th, 2026, between approximately 18:27 and 20:41 UTC, the GitHub Copilot service was degraded due to an issue with the Responses API of an upstream provider affecting the GPT-5.2, GPT-5.3-Codex, GPT-5.4, and GPT-5.5 models. Requests routed to these models via the Responses API returned elevated error rates, which also affected Copilot coding agent and Copilot code review. No other models were impacted. We mitigated the incident by shifting traffic away from the affected models while the upstream provider deployed a fix. GitHub is working to improve automated failover for the affected models and strengthen monitoring to prevent similar incidents in the future.
