Early Wednesday morning, Microsoft confirmed an outage of its Microsoft 365 cloud offerings—halting access for thousands of users spanning the globe and igniting frustrations across Twitter.

The services went down around 2 a.m. ET and were back up by 7:45 a.m. ET, according to the company’s support page. Microsoft’s internal investigation revealed a failed network update led to the blackout of critical services like Teams, Azure, Outlook, OneDrive and Sharepoint, among others.
