DENVER – Thousands of Comcast customers were without service after a dump truck damaged a fiber Tuesday.

The outage was first reported around 8:30 a.m., affecting about 9,000 customers in the southern part of Denver, according to Comcast spokesperson Alexandra Ballas. Service was fully restored by 7 p.m. Repair crews determined the damage was caused by a dump truck with its bed up, Ballas said.

Verizon also experienced service disruptions as a result. Its cell tower in the area relies on the damaged fiber, company spokesperson Meagan Dorsch said. Another tower nearby provided coverage for some customers, Dorsch said.
