Abstract:
According to CGTN news, Microsoft 365 experienced a global service outage. Outlook mailboxes, Teams meetings, and Copilot intelligent assistants collectively experienced connection failures, affecting 74 countries and regions around the world. A large number of corporate office operations have come to a standstill. Microsoft officials have clearly ruled out the possibility of cyber hacker attacks.
Microsoft executives respond to Outlook global outage
Data from the fault monitoring platform Downdetector shows that within an hour of the outage, users in the Americas, Europe, Asia and Africa concentrated on reporting access anomalies. The United States alone received about 130,000 Outlook failure feedback at its peak.
Microsoft executive Charles LaManna publicly apologized on social platforms and made it clear that there was no evidence that the incident was caused by a malicious cyber attack. Officials determined that the root cause of the failure was abnormally high loads on some infrastructure in multiple regions, resulting in large-scale connection errors. Microsoft issued a number of emergency solutions, suspending all version deployment changes, migrating traffic away from the faulty hardware, and restarting the affected servers.
However, the repair process was not smooth, and some disposal methods failed to achieve full recovery quickly. Microsoft explained that as server capacity is gradually restored, user devices will re-establish connections and services will be restored in batches.
