MS Teams was back for most users, the company said Thursday, after an hour-long outage disrupted the chat app for tens of thousands of customers worldwide.
The company cited an outage from a recent software update that “contained a broken connection to an internal storage service.”
“We are addressing any residual impact related to this event. Additionally, we are monitoring for any signs of failure until we are satisfied that all service functions are fully recovered,” the company said on its website.
MS Teams, used by more than 270 million people worldwide, is an integral part of daily operations for businesses and schools, who use the service to make calls, schedule meetings and organize their workflow.
The company did not disclose the number of users affected by the disruption, but outage tracking website Downdetector.com showed more than 4,800 incidents in the United States and more than 18,200 in Japan. The site tracks outages by gathering status reports from sources, including errors submitted by users on its platform.
During the outage, most users were unable to exchange messages or use app features. Many users took to Twitter to share updates and memes about the service disruption, with #MicrosoftTeams trending as a hashtag on the social media site.
“Microsoft Teams has come to a halt, and half the world works with #MicrosoftTeams,” one Twitter user said.
Microsoft has also confirmed some downstream impacts on several Microsoft 365 services with Teams integration, such as Microsoft Word, Office Online, and SharePoint Online.
The company has benefited from an increase in demand for remote business conferencing and messaging tools, with MS Teams becoming a key feature for organizations during the COVID-19 pandemic as people work from home.
Other big tech companies have also been hit by outages over the past year, with a nearly six-hour outage at Meta Platforms keeping WhatsApp, Instagram and Messenger out of reach of billions of users in October. last.
