Microsoft Teams has finally been restored after suffering a massive outage that lasted many hours!
Here was what happened…
Microsoft Teams Suffers Massive Outage!
On Wednesday, 20 July 2022, thousands of users were unable to access Microsoft Teams, and it continued into Thursdays, 21 July 2022.
This was a big problem, because Teams had become an integral part of daily operations for many businesses that had adapted to a hybrid work pattern during the COVID-19 pandemic.
Microsoft Teams users relied on the service to organise their workflow and communicate internally like making calls and messaging each other.
The MS Teams problem also affected other services downstream, with some users reporting issues with Microsoft Office 365 as well.
Microsoft acknowledged the downstream impact to multiple Office 365 services with Teams integration, like Microsoft Word, Office Online and SharePoint Online.
Why Microsoft Teams Suffered Such A Massive Outage!
After 1.5 hours after Teams went down, Microsoft announced that they found the root cause – “a recent deployment contained a broken connection to an internal storage device, which result in impact“.
That’s tech-speak for “we installed a system upgrade that pointed to a storage device that does not exist, so MS Teams stopped working“.
They quickly redirected traffic to “a healthy service to mitigate impact“, which have allowed unaffected users to continue using MS Teams, but it did not seem to help those who lost access.
Although they identified the root cause, restoration appears to be taking time. Two hours later, they could only report that “Microsoft Teams functionality is beginning to recover“, which they repeated two hours later.
In the meantime, affected MS Teams users are creatively expressing their “frustration” on social media…
Update @ 3:56 PM (GMT+8) : The Microsoft 365 team announced that Teams availability has “mostly recovered“, but “a few service features” still required attention.
