  1. resolved

    On August 1, 2026, between 17:47 UTC and 18:20 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 0.007%, while failures for Fable 5 peaked at 5.6%. 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.

    We are experiencing degraded availability for the Fable 5 model in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot.
