Microsoft Investigating Widespread Teams, Outlook, OneDrive Outages [Update: Fixed]

Microsoft is investigating a networking issue after tens of thousands of users around the world have reported being unable to access services like Teams and Outlook.

In a series of tweets posted on the Microsoft 365 Status Twitter account, Microsoft said it was taking steps to isolate the problem, but did not mention how widespread it was.

"We're investigating issues impacting multiple Microsoft 365 services," said Microsoft, to which it later added: "We've rolled back a network change that we believe is causing impact. We're monitoring the service as the rollback takes effect."

Online outage tracker Downdetector shows almost 4,000 people in India have been impacted and more than 5,000 in the UK reported that Outlook was inaccessible. Australia, Japan, and the United Arab Emirates have also seen spikes in outage reports.


Microsoft Teams is used by more than 280 million people globally across businesses and schools, according to the company. Other services impacted by the outage reportedly include Microsoft Exchange Online, SharePoint Online, and OneDrive for Business.

Microsoft also said it was investigating a connectivity issue with its cloud computing service, Azure, affecting what it called "a subset of users". We'll update this article once we learn more.

Update: Microsoft says it has now "confirmed that the impacted services have recovered and remain stable."

Just finished a Teams meeting.

Where's the outage when it is needed?

I'm sure Senior Network Architect.. lets call him "Brad" who was spontaneously laid off last week after working in the Operations team at Microsoft for 14 years could've stopped a bad network change.

But no whippersnapper Cloud Network Engineer, with two years of experience "Tom" definitely never saw that coming.

They just had a layoff, and this happens. What a coincidence.
And the night before the layoffs:


On Tuesday evening, Microsoft hosted an event. It was an intimate gathering of 50 or so people, including the company’s top executives, who got to while away the evening listening to a performance by the musical artist Sting, said people familiar with the event. https://www.wsj.com/livecoverage/davos2023/card/microsoft-hosted-sting-performance-in-davos-on-night-before-it-announced-layoffs-cRHO4k295pSWarvtfQRJ
I'm sure that wasn't cheap (with Sting being one of the richest musicians in the world) But cost aside, didn't they even think what the non-laid off employees left behind - running the company - would make of that?

Microsoft Azure is completely borked which is what they build on top of, as do a lot of other people.

Again.

Thank goodness we're on AWS. It's not our day to go down today ?

Edit: I love the downvote on this because it's actually factual and reported in the tech community elsewhere as well ??‍♂️
