Comcast Corp., the nation's second-largest Internet service provider, says it will set an official limit on the amount of data subscribers can download and upload each month.
The cable company says it will update its user agreement on Oct. 1 to say that users will be allowed 250 gigabytes of traffic per month.
Comcast has already reserved the right to cut off subscribers who use too much bandwidth each month, without specifying exactly what constitutes excessive use. Customers who go over the limit are contacted by the company and asked to curb their usage.
Comcast floated the idea of a 250 gigabyte cap in May. The company mentioned then that it might charge users $15 for every 10 gigabytes they go over, but the overage fee was missing in Thursday's announcement.
Comcast has said curbing the top users is necessary to keep the network fast and responsive.
