Resolved - On June 30th, 2025, between approximately 18:20 and 19:55 UTC, the Copilot service experienced a degradation of the Claude Sonnet 3.7 model due to an issue with our upstream provider. Users encountered elevated error rates when using Claude Sonnet 3.7. No other models were impacted.
The issue was resolved by a mitigation put in place by our provider. GitHub is working with our provider to further improve the resiliency of the service to prevent similar incidents in the future.
