NEW YORK – Email services operated by Yahoo and AOL were disrupted Monday, leaving large numbers of users unable to log in or send messages as engineers scrambled to diagnose the problem.

The interruption began just before 11 a.m. ET, when Downdetector saw a sharp spike in outage reports for both platforms. By early afternoon, complaints from Yahoo Mail users in the U.S. were approaching 2,000, while AOL Mail logged more than 1,000 reports and rising.
Some users may be experiencing issues accessing their AOL email accounts. Our team is actively investigating and will provide updates as more information becomes available.

Both companies acknowledged the issue on X, posting identical statements noting that “some users” were experiencing problems and that teams were working to resolve it.
Users say the problems vary — some cannot log in at all, while others report pages that load at a crawl or emails that refuse to send. One customer responding to Yahoo’s post said every message sent since late morning remained stuck “queued,” suggesting broader server delays beyond simple access failures.
The outage lands in the middle of Cyber Monday, a high-traffic period when many shoppers and businesses rely heavily on email confirmations and customer service communication. Yahoo Mail appears to be the hardest hit, with downtime patterns similar to a widespread outage the service suffered in July.
Yahoo is owned by Apollo Global Management and currently runs AOL Mail under the same infrastructure, though AOL is slated to be sold to Bending Spoons under a recently announced deal. Neither company offered a timeline for when full service will be restored.
For now, users are being advised to monitor official updates as technicians continue to work on the underlying issue.
