Several phone service providers, including AT&T, were down for many users across the United States early Thursday, according to Downdetector.com, which tracks telecommunication and internet disruptions.
The outage, which affected users in cities including Atlanta, Los Angeles and Dallas, was first reported around 3:30 a.m. Eastern time, and appeared to peak an hour later.
AT&T did not immediately respond to a request for comment. Outages on a smaller scale were reported by some users of Verizon, Cricket Wireless and FirstNet.
This is a developing story.
