Large-scale failure in business software "365", unable to send emails - Microsoft

[Silicon Valley Current Affairs] Microsoft (MS) announced on the 12th that a large-scale failure has occurred in its business software group "Microsoft 365." E-mail software such as Outlook has been affected, causing problems such as the inability to send and receive e-mails in many countries around the world.

A number of other services have also been affected, including the business chat software ``Teams'' and the artificial intelligence (AI) function ``CoPilot.'' MS explained on X (formerly Twitter) that some of its infrastructure is under stress in multiple regions. The problem was caused by multiple servers being unexpectedly unavailable, and efforts are being taken to distribute the load and restart the servers.

MS noted that some servers have been restored. However, there is no outlook for a complete recovery.

According to the system failure information site Down Detector, reports of failures began to increase rapidly around noon on the 12th, Western time (early morning on the 13th, Japan time).

The impact is widespread. According to US media, New York City's Emergency Management Department has announced that the city's email and online services rely on MS's systems, so there may be delays in communication.
