BREAKING: Microsoft hit by major global outage affecting Outlook, Teams, OneDrive and Copilot across its 365 suite, with reports peaking near 140,000 users and OpenAI and Anthropic also impacted. $MSFT

Microsoft went down worldwide, and hours later it still isn't fixed.

Outlook, Teams, OneDrive and Copilot all hit connectivity problems across the 365 suite. Downdetector logged nearly 140,000 reports at the peak, with users in the US, Japan and Singapore all locked out. Microsoft says a batch of servers became unexpectedly unavailable, which strained everything left standing, and it's now, quote, aggressively pursuing all pathways to reduce impact. That is corporate for we're not sure yet either.

The damage spread beyond Redmond. OpenAI and Anthropic both reported issues through their Microsoft connections, and an electric truck maker called Workhorse actually postponed its earnings because of the outage. The BBC understands this wasn't a cyber attack, just the plumbing giving way.

Here's what should worry Satya Nadella. Azure went down last month too. That's two global outages in a matter of weeks, and even restored services keep falling over again. The cloud everyone built their business on keeps raining.
