Inconsistent results when using the Haiku 4.5 model

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.

Investigating

The issues with our upstream model provider have been resolved, and Claude Haiku 4.5 is once again available in Copilot Chat and across IDE integrations.We will continue monitoring to ensure stability, but mitigation is complete.

Investigating

Usage of the Haiku 4.5 model with Copilot experiences is currently degraded. We are investigating and working to remediate. Other models should be unaffected.
