Breaking news: Microsoft’s Outlook suffers a global outage
MICROSOFT SAYS ITS FIXES AREN'T WORKING. THE SERVERS IT BRINGS BACK CAN GO DARK AGAIN THE MOMENT TRAFFIC HITS THEM.
More than 10 hours in, it still can't say what's triggering it.
→ 3:19pm ET — Microsoft: no recent change lines up with when this started
→ 5:09pm ET — "our actions taken thus far have not provided the anticipated relief"
→ 7:06pm ET — returned servers "can become unresponsive again once they receive traffic"
→ 7:06pm ET — it rebuilds some servers on a previous configuration and limits some traffic in some locations
→ 10:13pm ET — its own words: the changes are "not taking as expected"
First Microsoft blamed elevated load. Then it said servers went unexpectedly unavailable and dumped their load on the rest.
It paused all deployments, looked into high processor use, and restarted servers with a fix in place. The outage is still not over.
Outlook. Teams. SharePoint. OneDrive. Office on the web. Copilot.
Even Defender XDR, the security platform companies use to watch for attacks.
OpenAI and Anthropic say their Microsoft connectors broke too.
Reports hit 74 countries and territories in about an hour. Asia started its Friday with it still broken.
Electric truck maker Workhorse pushed its earnings from November 12 to November 16 because of it.
No sign of a cyberattack, Microsoft says. No traffic surge. No named cause.
Just a server fleet that won't stay up, and a company that can't say why.
This account stays on the Microsoft outage until it is fixed and will report the confirmed cause. Follow for that update.
