Cox said the problem is due to a "fiber cut."

Residents throughout Arizona have been reporting problems with their TV signal Wednesday evening.

A map on downdetector.com showed a Cox outage affecting most of Arizona and southern California, among other parts of the country. While most of the outage appeared resolved around 8 p.m., it continued to affect Arizona well after 10.

Cox Customer Care said the problem is due to a "fiber cut" and technicians are working to get services restored.
