Disruption with some GitHub services

Resolved

On December 18, 2025, between 16:25 UTC and 19:09 UTC the service underlying Copilot policies was degraded and users, organizations, and enterprises were not able to update any policies related to Copilot. No other GitHub services, including other Copilot services were impacted. This was due to a database migration causing a schema drift.We mitigated the incident by synchronizing the schema. We have hardened the service to make sure schema drift does not cause any further incidents, and will investigate improvements in our deployment pipeline to shorten time to mitigation in the future.

Investigating

Copilot is operating normally.

Investigating

We have observed full recovery with updating copilot policy settings, and are validating that that there is no further impact.

Investigating

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

Investigating

We have identified the source of this regression and are preparing a fix for deployment. We will update again in one hour.

Investigating

We are seeing an increase in errors on the User and Org policy settings page when updating policies. The errors are affecting the user copilot policies settings page, org copilot policies settings page when updating a policy.
