Timeline of updates

  1. resolved

    Between October 1st, 2025 at 1 AM UTC and October 2nd, 2025 at 10:33 PM UTC, the Copilot service experienced a degradation of the Gemini 2.5 Pro model due to an issue with our upstream provider. Before 15:53 UTC on October 1st, users experienced higher error rates with large context requests while using Gemini 2.5 Pro. After 15:53 UTC and until 10:33 PM UTC on October 2nd, requests were restricted to smaller context windows when using Gemini 2.5. Pro. No other models were impacted. The issue was resolved by a mitigation put in place by our provider. GitHub is collaborating with our provider to enhance communication and improve the ability to reproduce issues with the aim to reduce resolution time.
