Microsoft 365 went dark for hours. $MSFT barely flinched.

From about 1pm ET Thursday, Outlook, Teams, Copilot, SharePoint and OneDrive threw connection errors worldwide. Downdetector reports for Outlook peaked around 130,000. Microsoft says a number of servers unexpectedly went offline and overloaded the rest, with no sign of a cyberattack. Recovery was still partial hours later.

Market link: 365 is one of Microsoft's core business products, and companies everywhere run on it.

The move: $MSFT traded near $529 just before the outage, faded to close at $523.00, still +0.4% on the day. After hours it slipped to $521.09 (07:59 ICT).

Does a big outage ever really hurt a mega-cap stock, or is it just noise?
