Microsoft Teams is down around the world, and it’s already been eight hours

Is it a joyous outage where you get to relax, or something mission critical going wrong? Either way, “a portion” of Microsoft Teams is down — with outages in North America, South America, Europe, the Middle East, and Africa, according to a status update from Microsoft’s official account.
So yeah, if you can’t communicate with your colleagues right now via Microsoft’s biz comm platform, that’s probably why. Some users are reportedly not able to log into Teams, while others may see missing messages, missing attachments, delays — and fixing it is taking a while.
As of 8PM ET Friday, over eight hours after the outage began, Microsoft has not yet sent an all-clear. Here’s the latest update:
We’re continuing to apply mitigations across the affected infrastructure and our telemetry is showing additional improvement in the user experience, though many customers are still affected by this issue. We’re also working to apply fixes to address individual affected Teams features in parallel while our broader remediation strategy is ongoing. We’re evaluating any and all additional workstreams that will allow us to reduce the impact to those customers that are still affected.
The spike in problem reports at DownDetector suggests this had been going on for at least three hours at the time we published our story, and Microsoft officially recognized the issue at around 11:45AM ET. The company says it identified “a networking issue impacting a portion of the Teams service,” and said it would begin failovers to resolve the problem.
Four hours later, though, Microsoft reported that “Our failover operation did not provide immediate relief to all end users in North and South America regions.” While the DownDetector spike has subsided, it’s not clear whether that’s because services are substantially restored or because there’s no point complaining anymore.
Our failover operation did not provide immediate relief to all end users in North and South America regions. However, we’re seeing improvements as we continue to optimize traffic patterns and apply configuration changes intended to reduce (cont) https://t.co/yed1jveb6I

If you’ve got access to a Microsoft Teams admin console, you can check the status at TM710344, though I imagine most admins already know that by now.
For hours after the outage began, Microsoft’s status page was all green, suggesting Microsoft Teams was fine, but it updated with this description shortly before 2PM ET:
Title: Some users may experience multiple issues with their Microsoft Teams
User impact: Users may experience multiple issues with their Microsoft Teams.
More info: Affected scenarios include, but aren’t limited to:
– Users performing a cold boot may not able to log into teams and will see an “oops” page.
– Users logging in or unlocking their devices after some time may see missing messages.
– Users may fail to load messages in channels and chats
– Users are unable to view or download their media (images, videos, audio, call recordings, code snippets)
– Some messages may experience delays being sent
– Call Recordings might take longer to appear in user’s OneDrive for Business and SharePoint Online
– Bots may be unable to download attachments
– Sending and receiving read receipt notifications may be delayed
Current status: Our monitoring systems alerted us to an issue where users may experience various impact scenarios in Microsoft Teams, outlined in the More info section above. We’ve identified that a portion of the Microsoft Teams service is experiencing a networking issue. We’ve completed a failover in the Europe, Middle East, and Africa (EMEA) region and telemetry is showing improvement. We’re continuing work to failover service traffic in all affected regions to remediate impact.

IT admins saw a similar message in their dashboards around 1PM ET, according to an r/sysadmin user:
Microsoft Teams had a four-hour outage almost exactly a year ago. It had a pair of large outages in 2021, and ones in 2020 and in 2019, too, but this eight-hour-plus outage may take the cake — depending on how many people were affected, anyhow.
Update, 8:00PM ET: Added that the outage is still ongoing, and Microsoft’s latest update.
