Is Microsoft Copilot not working today? Is AI tool down, why is there a 'sorry' message as issues spike on DownDetector
Microsoft's AI-powered digital assistant, Copilot, went down for users in the UK and Europe on 9 December 2025.
In a report by BleepingComputer, Microsoft acknowledged the problem, stating that it was caused by a 'capacity scaling issue' and that they are already looking into it. Microsoft addressed the public on X.
It said: “We're investigating an issue in which users in the United Kingdom may be unable to access Microsoft Copilot, or experience degraded functionality with some features.” The report also includes the outage, under the incident code CP1193544, which rendered users unable to access copilot.cloud.microsoft, MS Copilot integrations for MS 365, among others.
Users said that they were getting a similar error message that read, 'Sorry, I wasn't able to respond to that. Is there something else I can help with?'. The high demand likely caused the system to collapse.
Microsoft added: “We've identified an issue impacting service autoscaling to meet demand. We're manually scaling capacity to improve service availability, and we're monitoring this closely to ensure the expected outcome is achieved. For more information, please see CP1193544 in the admin centre.”
DownDetector saw a huge spike in users reporting problems with Microsoft Copilot on Tuesday. This morning (Wednesday 10 December) there seems to be a spike in reports, suggesting that it is still down for some users.
