Microsoft, AT&T customers hit with outages — what to know

The networks for Microsoft Teams and Outlook, as well as AT&T, are back to functioning normally after suffering widespread outages on Thursday morning, both companies announced.

About 4,000 outages on Microsoft Teams were reported at 9 a.m. ET, increasing from less than 300 an hour earlier. A lesser outage for Microsoft Outlook was also noted by Downdetector, with reports of more than 1,000 outages at 9 a.m. ET.

Reports of an outage with landline internet and mobile internet for AT&T also jumped to more than 4,000 at 9 a.m. ET on Sept. 12, according to Downdetector.

The issue appeared to be largely resolved by 11 a.m. ET, per Downdetector’s charts

"We experienced a brief disruption connecting to some Microsoft services on our network," an AT&T spokesperson said in a statement shared obtained by TODAY.com. "The issue has been resolved and connections are operating normally.”

The spokesperson added that the company is investigating the disruption and there is "no indication of foul play."

Microsoft shared in an update on X at 10:45 a.m. ET that it has monitored its systems and "impact has been remediated."

The company had reported an issue on its Service Health Status page at 7:46 a.m. ET indicating that "users may be unable to access one or more Microsoft 365 services."

It's unclear if it was related to the AT&T outage, but Microsoft said the issue was due to a third-party provider.

"We’ve worked with the third-party Internet Service Provider (ISP) and confirmed that a change within their managed-environment resulted in impact," the notice said. "The ISP has reverted the change and we’re now seeing signs of recovery. We’re continuing to monitor network telemetry data to ensure a full recovery."

AT&T previously had a widespread outage in February that affected more than 60,000 customers.
