AT&T has agreed to pay a $5.25 million fine to settle an investigation into a pair of nationwide 911 outages that occurred in early 2017. The Federal Communications Commission said the first outage, on March 8th, lasted about five hours and affected 12,600 callers. The second, on May 1st, lasted 47 minutes and resulted in 2,600 failed 911 calls.

“Such preventable outages are unacceptable,” the FCC wrote in a statement announcing the settlement. “Robust and reliable 911 service is a national priority, as repeatedly expressed by both Congress and the Commission.”
