Disruption with some Copilot services

We are investigating reports of impacted performance for some GitHub services.

We are experiencing issues with upstream model providers resulting in a degraded experience across Copilot services. The team is actively investigating the issue.

We are experiencing degraded availability for the GPT-5.3-Codex, GPT-5.6 Luna, GPT-6.1 Sol, GPT-5.6 Terra, GPT-6 Luna, and MAI Code 1.1 Flash models 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 to continue using Copilot.

We are experiencing degraded availability for the GPT-5.3-Codex, GPT-5.6 Luna, GPT-6.1 Sol, GPT-5.6 Terra, GPT-6 Luna, and MAI Code 1.1 Flash models in Copilot products and IDE surfaces. We have identified the root cause and working to apply a mitigation. While we work to resolve the issue we recommend choosing another model to continue using Copilot.

We have applied the mitigation and are seeing signs of recovery. We will continue to monitor and expect full resolution soon.

Copilot is experiencing degraded performance. We are continuing to investigate.

The degradation affecting Copilot has been mitigated. We are monitoring to ensure stability.

This incident has been resolved. Thank you for your patience and understanding as we addressed this issue. A detailed root cause analysis will be shared as soon as it is available.
