On November 12, 2026, a global outage of Microsoft services, including Outlook, Teams, and Copilot, began affecting numerous organizations across the UK, including the NHS, police forces, and local councils. Microsoft attributed the disruption to a higher-than-usual stress on its servers, with recovery efforts ongoing. Key services such as email and messaging were severely impacted, leading to delays in critical communications and operations. NHS trusts advised patients to attend appointments unless otherwise notified, while police forces urged the public to report emergencies via phone rather than online. As of November 13, Microsoft reported improvements in service availability, but intermittent issues persisted. The outage has raised concerns about the reliance on a single technology provider for essential services.
