Cox expands home Internet data caps, while CenturyLink abandons them

Cox, the third largest US cable company, started charging overage fees to customers in four more states.

Cox, which operates in 18 states with about six million residential and business customers, brought overage fees to Arizona, Louisiana, Nevada, and Oklahoma. Cox was already enforcing data caps and overage fees in Arkansas, Connecticut, Florida, Georgia, Idaho, Iowa, Kansas, Nebraska, and Ohio. California, Rhode Island, and Virginia technically have monthly caps but no enforcement of overage fees, according to Cox's list of data caps by location. Massachusetts and North Carolina seem to be exempt from the Cox data caps altogether. CenturyLink recently ended an experiment with data caps and is giving bill credits to customers in the state of Washington who were charged overage fees during the yearlong trial.
