    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.
