New York Attorney General Letitia James said Thursday that her office is investigating the cause of AT&T’s wireless outages last week that lasted up to 12 hours and the carrier’s response.
The Federal Communications Commission is also investigating the Feb. 22 outage.
AT&T said Saturday it would provide affected consumers with a $5 bill credit, but did not say how many customers temporarily lost service. Local officials said the power outage affected some emergency calls.
AT&T’s initial investigation determined that the outage was caused by incorrectly applying and executing processes during network expansion efforts and ruled out a cyberattack, the company said. AT&T says its 5G network reaches about 290 million people across the United States.
“A nationwide power outage is not only an inconvenience, but it can also be dangerous, and it’s important to protect consumers when a power outage occurs,” James said.
AT&T did not immediately comment.
