TREE NEWS update: Microsoft suffered a widespread service outage on Thursday, affecting thousands of users across multiple regions, with Microsoft 365 and Outlook disrupted from shortly before 2 a.m. Beijing time on the 13th. Amazon Web Services and Google users also reported service interruptions on outage-tracking site Downdetector. Microsoft said the issue centered on Exchange Online and was caused by some servers becoming unexpectedly unavailable, increasing load on remaining infrastructure.
Microsoft 365 outage hits thousands; AWS and Google also report issues
The simultaneous disruption across Microsoft, AWS and Google, even if only Microsoft detailed a cause, raises a question about shared dependency or coincidence that the item does not resolve. For enterprises relying on Microsoft 365 and Exchange Online, the incident underscores how a single infrastructure failure can cascade through email and productivity tools. Whether the AWS and Google reports reflect the same root cause or unrelated events is the open question worth watching.
