CNA – Microsoft said yesterday it was investigating an issue impacting multiple services including Teams and Outlook, with outage reports saying the platforms were down for thousands of users globally.
In an update at 4.15pm, the tech giant said that it identified “a potential networking issue and are reviewing telemetry to determine the next troubleshooting steps”.
At 5.06pm, it said the problem had been isolated to networking configuration issues. Twenty minutes later, Microsoft tweeted that it had rolled back a network change believed to be the cause of the problem.
“We’re monitoring the service as the rollback takes effect,” the company said.
Microsoft’s cloud unit Azure also tweeted about the networking issue, and said that a subset of users were experiencing problems with the platform.
Microsoft did not disclose the number of users affected by the disruption, but data from outage tracking website Downdetector showed more than 3,900 incidents in India and over 900 in Japan.
Outage reports also spiked in Australia, Britain and the United Arab Emirates.
The Downdetector site tracks outages by collating status reports from sources including user-submitted errors on its platform.
During the outage, most users were unable to exchange messages, join calls or use any features of the Teams application. Many users took to Twitter to share updates about the service disruption, with #MicrosoftTeams trending as a hashtag on the social media site.
Microsoft Teams, used by over 280 million people globally, forms an integral part of daily operations for businesses and schools, which use the service to make calls, schedule meetings and organise their workflow.
Among the other services affected were Microsoft Exchange Online, SharePoint Online, OneDrive for Business, according to the company’s status page.
