About this tag
The cloud outage tag covers reports on Microsoft 365 service disruptions affecting workplace communication, collaboration, storage, documents, automation, administration, and AI features. Recent coverage follows incidents involving Teams, Outlook, SharePoint, Excel, Copilot, sign-ins, and the Microsoft 365 admin center. The articles examine provider-side failures, including routing problems and degraded network paths, rather than assuming every Microsoft product is unavailable. They also outline practical guidance for administrators, such as checking tenant Service Health, preserving working sessions, avoiding unnecessary password or multifactor changes, and using out-of-band communications while Microsoft investigates and restores affected services.
