The issues with our upstream model provider have been resolved, and GPT-5.6 Luna is once again available in Copilot products and IDE surfaces.<br />We will continue monitoring to ensure stability, but mitigation is complete.

We keep working with our upstream model provider, and are observing recovery. We continue monitoring to ensure stability.

We are experiencing degraded availability for the GPT-5.6 Luna 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 external ai model provider has resolved the issues, and we have verified Copilot's traffic is fully recovered.

The external AI model provider is continuing to investigate.

The external AI model provider has identified the issue and is working to resolve.

We are investigating increased error rates affecting GitHub Copilot requests to external AI model providers. Some users may experience failures or degraded performance when using Copilot features.

We are seeing increased error rates with requests to specific model providers.

On July 29, 2026, from 14:51 UTC to 15:28 UTC, GitHub Actions experienced elevated REST API request timeouts and errors, failures registering runners, and delayed workflow run starts for customers whose traffic was served by a single infrastructure site. This was caused by an under-provisioned internal Actions service in that site: under increased load its instances ran out of memory and became unresponsive, and because Actions API requests wait synchronously on that service, requests routed through the affected site stalled and timed out. During the incident, approximately 2% of workflows were delayed. Requests served by other sites remained unaffected. Both standard and larger hosted runners routed through the affected site could see delayed job starts. <br /><br />The issue was mitigated by scaling out the runner-administration service in the affected site and increasing the replica count, which restored API availability and returned workflow run starts to normal. We are working to add horizontal autoscaling, memory-saturation alerting, and scaling-forecast monitoring for this service, along with responder playbooks, to reduce the likelihood of similar issues in the future.

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

We are investigating an issue affecting GitHub Actions. Some customers may experience timeouts or failures with runner registration and workflow runs may be delayed during startup. Our team is actively working to mitigate the impact by scaling capacity across additional infrastructure.
