AT&T offering credit to accounts of customers affected by network outage

(CNN) – AT&T is reimbursing customers for Thursday’s network outage.

Tens of thousands of customers last Thursday dealt with error messages or no service connection.

The mobile network says it wanted to recognize the frustration the outage caused people.

AT&T says it will issue a $5 credit to “potentially impacted” wireless customers, which it says is the “average cost of a full day of service.”

While regional disruptions to wireless service happens occasionally, prolonged nationwide outages are rare.

The Federal Communications Commission says it is investigating the incident.
