Affected components

• Copilot AI Model Providers

1. resolvedJul 30, 2026, 10:12 UTC

   On July 30, 2026, the Claude Fable 5 model in GitHub Copilot experienced degraded availability for approximately 73 minutes, from 08:33 to 09:46 UTC. During this time, requests to Claude Fable 5 in Copilot chat and IDE surfaces frequently failed or timed out. This was caused by an issue with an upstream model provider. Other Copilot models were not affected, and users could continue working by selecting another model or 'Auto'. Availability for Claude Fable 5 fully recovered once the provider resolved their outage at 09:46 UTC, and we confirmed resolution at 10:12 UTC.
