Starting in January, Comcast plans to charge home internet customers in northeastern US states for going over 1.2TB of data in a month—a cap that’s already in effect for customers on non-unlimited plans in other parts of the country. The affected states include Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Vermont, Virginia, West Virginia, and the District of Columbia, as well as parts of North Carolina and Ohio.
