Microsoft says an outage with Microsoft 365 services mitigated

By

Microsoft said on Thursday that it has alleviated the problem after many users were unable to access Microsoft 365 services and features, including workplace messaging apps Teams and Azure.

“We have confirmed that the underlying DNS outage has been mitigated. Currently we re validating the recovery of the downstream Microsoft 365 services,” it said in a tweet here.

Domain Name System (DNS) is effectively an address book of the internet which enables computers to match website addresses with the correct server.

Earlier, outage tracking website Downdetector showed over 8,000 incidents of people reporting issues with its widely used Teams workplace messaging app.

Downdetector only tracks downtime by collating status reports from a range of sources, including errors submitted by users on its platform. The outage may affect more users.
