Microsoft outage disrupts services worldwide, no cyberattack found

A major Microsoft cloud outage disrupted Outlook, Teams, SharePoint, and other Microsoft 365 services globally, affecting users, businesses, schools, and government agencies. Microsoft stated it found no signs of a cyberattack and gradually restored infrastructure. The failure was caused by a mass server malfunction, not increased traffic, according to Microsoft. Downdetector reported over 130,000 complaints about Outlook in the US, with issues also in Australia, Japan, India, and other Asia-Pacific regions. Third-party companies like OpenAI and Anthropic were also impacted. This is the second major Microsoft 365 outage this year, highlighting risks of relying on a single digital infrastructure provider. Experts emphasize the need for backup communication channels and contingency plans.
