GoKawiilMicrosoft 365 outage lasted over 22 hours, hit 70+ countries
A Microsoft 365 outage lasting more than 22 hours disrupted Outlook and other services for roughly 430 million users worldwide, with impacts reported in over 70 countries. Microsoft said the cause was routine automated checks that took servers offline and overloaded remaining ones, not a cyber-attack, and has since apologised. Affected organisations included the US House of Representatives, Australian intelligence agencies, Singapore's courts and Indian airline support desks.

The scale of disruption underscores how dependent businesses, governments and critical infrastructure have become on a small number of major cloud providers, according to Small Business Charter director Flora Hamilton. AI strategist Walter Pasquarelli suggests that as AI tools become more integrated into email and files, similar outages could have even wider-reaching effects in future. The incident may prompt renewed scrutiny of concentration risk in cloud services.
