Before: 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.
After: On October 28, 2026, between 13:52 and 15:24 UTC, Copilot users saw errors when using several GPT-family models and the MAI Code 1.1 Flash model. Affected experiences included Copilot Chat in IDEs and on GitHub.com, the Copilot CLI, Copilot Code Review, the Copilot Coding Agent, Code Scanning Autofix, and Code Quality. About 9.73% of requests to the affected models failed, with a peak of about 36.97% at the start of the incident. The errors happened because a credential that we use to authenticate with an upstream model provider became invalid. We mitigated the incident by replacing the credential and redeploying the service. We are strengthening how we manage credentials for upstream providers to prevent this type of failure, returning retryable errors when an upstream provider rejects a request, and improving our monitoring so that we detect and mitigate this type of problem faster in the future.

Archive proof

Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves this record existed by then and has not been changed since, by anyone, Rewindex included.

How the archive is checked, and what it cannot prove.

Rewindex captured a newer version after the last checkpoint; the next run () commits it.
