Timeline of updates
- resolved
From October 28th at 16:03 UTC until 17:11 UTC, the Copilot service experienced degradation due to an infrastructure issue which impacted the Claude Haiku 4.5 model, leading to a spike in errors affecting 1% of users. No other models were impacted. The incident was caused due to an outage with an upstream provider. We are working to improve redundancy during future occurrences.
From GitHub’s published incident history: for incidents before Rewindex began polling this status page, only the final update text is available.

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.

This incident predates live tracking (October 17, 2026). It came from the vendor’s own published history, which is not covered by checkpoints.
