Microsoft investigates Copilot outage affecting users in Europe

Microsoft reported a regional outage affecting Copilot in the UK/Europe caused by capacity scaling and load-balancing issues, leading to access errors and degraded functionality; the company mitigated the incident by manually scaling capacity and reverting a policy change, ultimately restoring service. Separate from this, some admins experienced errors accessing Microsoft Defender for Endpoint features, and the report references a prior Defender XDR portal outage.
