Confirm your retries, queues and scheduled jobs caught up after the 30m it lasted.
Anything that failed between 2026-06-16 17:45 UTC and 2026-06-16 18:15 UTC may need a replay.

We are experiencing degraded availability for the Opus 4.8 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.

The issues with our upstream model provider have been resolved, and Opus 4.8 is once again available in Copilot products and IDE surfaces. We will continue monitoring to ensure stability, but mitigation is complete.

On June 16, 2026, between 17:20 UTC and 18:15 UTC, the Opus 4.8 model experienced degraded availability in GitHub Copilot. During this window, some requests to Opus 4.8 failed or errored. Other Copilot models were not affected and remained available as alternatives. This was caused by an issue with an upstream model provider. The upstream provider resolved the issue, and we monitored Opus 4.8 until success rates returned to normal. The incident is fully resolved.
