On Monday US time, Microsoft's 365 services took a hit around the world after an authentication update went wrong. Such updates are normally not carried out on Mondays.
In a statement on its Azure status page, Microsoft said preliminary analysis of the incident showed that "an error occurred in the rotation of keys used to support Azure AD’s use of OpenID, and other, Identity standard protocols for cryptographic signing operations".
"Metadata about the signing keys is published by Azure AD to a global location in line with Internet Identity standard protocols. Once the public metadata was changed at 19:00 UTC (6am AEDT on Tuesday), applications using these protocols with Azure AD began to pick up the new metadata and stopped trusting tokens/assertions signed with the key that was removed. At that point, end users were no longer able to access those applications."
The issue was rectfied by 21:05 UTC (8.05 AEDT on Tuesday). "Service telemetry identified the problem, and the engineering team was automatically engaged. The key removal operation was identified as the cause, and the key metadata was rolled back to its prior state at 21:05 UTC," the company said.
You guys going to actually apologize? How about your utter failure on the Snyder Cut Virtual Premier?— ROR Bacon (7-3-1) (@JGrwnger) March 16, 2021
But complaints continue to pour in, many about Teams not working as expected, and Sharepoint Online and OneDrive playing up as well.
One Twitter user, Umar Tariq, commented sarcastically: "Until this issue is resolved you can think about moving to @awscloud and have a seamless connectivity with continuous business continuation :) @ericgales @JeffBezos."
