Federal Communications Commission Chairman Ajit Pai called the outage that began Thursday “completely unacceptable” because people who need help couldn’t use the emergency number.
“Its breadth and duration are particularly troubling,” he said.
The commission’s Public Safety and Homeland Security Bureau will investigate the cause and effect of the outage, he said.
CenturyLink spokeswoman Debra Peterson said the outage “is not related to hacking,” but she declined further comment.
The company said on Twitter that it’s working to restore service and appears to be making progress. It hasn’t provided a cause for the problems.
“Where CenturyLink is the 911 service provider 911 calls are completing,” the company said in a tweet.
