Update timeline

  1. identified Dec 09, 2025, 04:18 PM UTC

    Microsoft have reported that some users may encounter issues accessing Copilot, or experience a degraded service. If affected, Copilot may respond with "Sorry, I wasn't able to respond to that. Is there something else I can help you with?" Microsoft have identified a cause, and whilst they are working to alleviate the impact and rectifying the situation, users may continue to experience issues on an intermittent basis whilst throttling of requests continues - therefore re-trying after a brief pause may result in success on subsequent attempts. We will provide further updates on the progress Microsoft is making in resolving this as they become available.

  2. resolved Dec 10, 2025, 09:50 AM UTC

    Microsoft have confirmed that they have resolved the issue that was affecting Copilot and normal service has resumed.
