  2. investigating

  3. resolved

    On July 16, 2026, GitHub Copilot users experienced elevated errors when using Claude Fable 5 from 17:33 UTC until mitigation at 22:04 UTC. The average error rate was 1.4%, with a maximum error rate of 30.85%. The issue was caused by degradation at an upstream model provider; other Copilot models were not significantly affected, and users could avoid the impact by selecting another model or Auto. Service recovered after the provider mitigated the degradation.
