Starting Oct. 1, Comcast home internet service customers will be limited to 250GB of data transfer per month. According to the company, the move is in response to heavy usage by some customers that can cause network congestion. The company stresses that it has no similar plans for business users.
Charlie Douglas, director of corporate communications for Comcast's online services, says, "The amount of data measured is aggregate monthly usage of uploads and downloads."
Comcast has added some teeth to the usage limit as well: The first time the limit is exceeded, the offending customer will receive a phone call from a Comcast representative. The second violation will result in a shutdown of internet service for one year.
