Thousands of Microsoft 365 customers worldwide reported issues with Outlook, Teams and other services on Monday.

Some Verizon customers have been hit by a service outage.

AT&T says the hourslong outage to its U.S. cellphone network appeared to be the result of a technical error, not a malicious attack.

T-Mobile peaked with 119,138 users reporting problems, according to Downdetector. Users across social media had also been vocal about cell service issues. Sprint peaked at 1,794.
