Rogers CEO Nadir Mohamed apologizes for major wireless outage

The chief executive of Rogers Communications is apologizing to the company's wireless customers across the country after part of its network went dark.

The telecom giant (TSX:RCI.B) restored its wireless voice and text messaging services late Wednesday night after the major outage, but president and CEO Nadir Mohamed says recognizes that the service breakdown was "unacceptable."

Mohamed said technicians worked as quickly as possible to restore service, adding that he sincerely apologizes for this "significant inconvenience."

Rogers and Fido postpaid wireless customers, those on a contract and who pay monthly, will receive a credit on their bills for one day of service because of the outage.

The company's data services did not appear to be affected by the outage.

Rogers has not yet determined what caused the problem, which produced a torrent of negative customer reaction on social media networks. The company has about 10 million wireless customers across Canada.
