AT&T service is out for some users.

A nationwide AT&T outage again left some customers without communication on Tuesday.
In a statement to CNN, the company said many AT&T customers are experiencing issues completing calls between carriers, which also means customers of rival services can’t call AT&T customers.
Calls between AT&T customers continue to work, but some subscribers have complained on social media that their service has been completely interrupted, the company said. Internet connections are not affected.
“Carriers are working as quickly as possible to diagnose and resolve the issue,” a company spokesman said.
AT&T has not released the number of affected customers, but the website Down Detector said it saw a spike in reports of problems using the service starting around 1 p.m. ET. The number grew in the hours that followed. But by around 6 p.m. ET, the number of reported incidents had started to taper off, Down Detector said.
The site lists New York City, Chicago, Philadelphia, Dallas, Pittsburgh and Indianapolis as cities with the most reported issues.
Thousands of Verizon customers also reported service outages on Downdetector on Tuesday due to interoperability issues.
AT&T told CNN that calls to 911 were going through despite several locations, including Camden County, Georgia, and Scranton, Pennsylvania, posting social media warnings that an outage was preventing calls to 911. AT&T told CNN that the call was received in error after a template for such a notification was triggered and sent out. AT&T said it was investigating why that happened.
The outage comes less than four months after a major outage that took AT&T’s network offline for nearly 12 hours. In February, an AT&T network outage left tens of thousands of AT&T customers in the U.S. unable to make calls, send texts, contact emergency services or access the internet.
In March, the telecommunications company announced it had been hacked in a separate incident and that the stolen data included account holders’ Social Security numbers and other information.
