JagsLive writes with this story from PC Magazine: "Comcast has confirmed that all residential customers will be subject to a 250 gigabyte per month data limit starting October 1. 'This is the same system we have in place today,' Comcast wrote in an amendment to its acceptable use policy. 'The only difference is that we will now provide a limit by which a customer may be contacted.' The cable provider insisted that 250 GB is "an extremely large amount of data, much more than a typical residential customer uses on a monthly basis. ... As part of our pre-existing policy, we will continue to contact the top users of our high-speed Internet service and ask them to curb their usage,' Comcast said Thursday. 'If a customer uses more than 250 GB and is one of the top users of our service, he or she may be contacted by Comcast to notify them of excessive use,' according to the AUP."
