AU - Disruption with some GitHub services
Incident
Report for GitHub Enterprise Cloud Australia
Resolved
On July 2nd, 2025, between approximately 08:40 and 10:16 UTC, the Copilot service experienced degradation due to an infrastructure issue which impacted the Claude Sonnet 4 model, leading to a spike in errors. No other models were impacted.
The issue was mitigated by rebalancing load within our infrastructure. GitHub is working to further improve the resiliency of the service to prevent similar incidents in the future.

Update
We are no longer experiencing degradation—Claude Sonnet 4 is once again available in Copilot Chat and across IDE integrations.
We will continue monitoring to ensure stability, but mitigation is complete.
