Issue Status: RESOLVED

Issue Description: Users may have received response failures or a degraded experience when using Researcher in Copilot.

Current Update: 03/07/2026 09:24:00 AM – After monitoring the environment, Microsoft has confirmed that this issue has been resolved by their actions to optimize traffic distribution and performance parameters on the affected infrastructure.

Scope of impact: Any user who attempted to submit or process Researcher requests in Copilot may have received response failures or degraded performance.

Root cause: A recent service configuration change caused a section of service infrastructure that facilitates Researcher in Copilot to perform below acceptable performance thresholds, which resulted in impact.

Next Steps: Microsoft are continuing their analysis of the impacting configuration change to better identify why it resulted in impact and how they can bolster our check in process in an effort to prevent similar issues in the future.
