Microsoft 365 restored after 38-hour global outage hits 74 countries

Microsoft has announced the full restoration of its Microsoft 365 services, including Outlook, Teams, and Copilot, after a global outage lasting nearly 38 hours. The incident, which began Thursday at 5:17 PM, affected users in 74 countries, including hospitals, airlines, and banks. Microsoft attributed the outage to a defect introduced during a network capacity increase, which manifested after a subsequent network change, causing servers to fail in a cascade. No malicious activity was detected. The company has promised a detailed post-incident report, and affected enterprise customers may request service credits under their service level agreements. In France, the outage has intensified the debate over government dependence on American digital tools, with the state promoting alternatives like Visio and La Suite. Microsoft is also monitoring the delivery of delayed emails, and users are advised to check for failed messages and be wary of phishing scams referencing the incident.
