Microsoft has confirmed a major outage to its Microsoft Teams group collaboration service.

Users began reporting issues accessing the software at around 10pm Eastern Time in the US on Wednesday, with more than 7000 reports just before midnight, according to DownDetector.

There were also more than 150 reports of outages on the Microsoft 365 platform.

“We’ve received reports of users being unable to access Microsoft Teams or leverage any features,” Microsoft wrote on Twitter. “We’re investigating the issue.”

The company later added, “We’ve determined that a recent deployment contained a broken connection to an internal storage service, which has resulted in impact. We’re working to direct traffic to a healthy service to mitigate impact.”

The company directed users to the admin centre to receive further updates.

Last October, Meta was hit with a massive global outage affecting Facebook, Instagram and WhatsApp for nearly six hours.

That outage was blamed on a Domain Name System (DNS) failure.

A DNS connects domain names to the right IP addresses so that people can access websites.

Earlier in 2021, an outage at a major DNS operator took out huge swathes of the internet briefly.
