Copilot: Issues with accessing or degraded service

Incident Report for Cardiff University

Identified

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.
