On July 29, 2026, between 19:45 UTC and 21:51 UTC, users of the Fable 5 model in GitHub Copilot experienced increased request failures and latency. The average failure rate across all Copilot requests was 0.006%, while failures for Fable 5 peaked at 21%. Other models remained available. This was caused by degradation of an upstream model provider.<br /><br />The affected endpoint recovered, and we monitored the service until error rates and latency returned to normal levels. We are working to add endpoint redundancy to mitigate similar provider issues in the future.
The external ai model provider has resolved the issues, and we have verified Copilot's traffic is fully recovered.
The external AI model provider is continuing to investigate.
