## Timeline of updates

- **resolved** 2026-08-01 12:30 UTC: On August 1st, 2026, the GPT-5.6 Luna model in GitHub Copilot experienced degraded availability in intermittent time intervals between ~08:05 UTC and ~16:30 UTC. Specifically the timeframes observed were 10:00-10:20 UTC, 10:45-11:50 UTC, 13:00-14:25 UTC, and 16:00-16:30 UTC. During this time, requests to GPT-5.6 Luna 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 GPT-5.6 Luna fully recovered once the provider resolved their outage at 16:30 UTC.
