DENVER (AP) – A cut in a fiber-optic line has knocked out cellular phone service to customers across a large part of northwest Colorado.

CenturyLink spokesman John Hall says the company is still trying to determine how the line was damaged between Frisco and Dillon on Monday afternoon. He says Centurylink did not have a crew working in the area at the time.

Hall said the cut line knocked out cell phone service for Verizon, AT&T, Cricket, Sprint and T-Mobile customers. It affected 32 cell phone tower locations northwest of Frisco, including Steamboat Springs, Craig and Winter Park.

Hall says the cut also disrupted long-distance service for land lines.
