Microsoft 365 outage disrupts global services for over 24 hours

A global outage of Microsoft 365 services, including Outlook, Teams, and Copilot, disrupted millions of businesses and public entities for over 24 hours starting Thursday, with recovery still ongoing. The company attributed the issue to a technical problem from a network capacity update, ruling out cybersecurity or AI causes. Experts describe a "cascade effect" where overloaded servers failed, and recovery is being done gradually to prevent further collapses. The outage impacted Portuguese government services, healthcare, and transport, with global effects on airlines and financial markets. Authorities warn of potential phishing scams exploiting the incident, and experts note the event highlights risks of single-platform dependency.
