Comcast cuts off customer for going over 250GB of legitimate use

The ISP has to maintain and upgrade thousands of miles of physical plant to deliver data to customer's homes in the geographic regions they cover. For a typical cable ISP for instance there's about 3-5 miles of copper between your modem and the the fiber node and typically dozens of miles between the fiber node and the provider's headend/datacenter where they uplink to the Internet -- which incidentally for smaller rural ISPs may itself be hundreds of miles away from competitive rates on data. Going back to the cost of maintaing/upgrading the infrastructure a small plant of only ~1000 miles typically requires at least a dozen full time employees simply to maintain it day to day and that's not including things like management, network engineers, customer service, technical support, equipment, contracted labour, customer installation, etc. On top of that you've got the cost of leasing access to the poles/underground conduits and the cost of powering the 3-5 miles of plant plus whatever operational costs you have to put gas into your fleet of vehicles, the cost of the vehicles themselves, insurance, etc. When you put this all together you're looking at some pretty huge overhead on the consumer side of Internet access plus whatever profit the company wants to make to justify all of the above. It's not a charity after all.

The vast majority - more than 99% - of our customers will not be impacted by a 250 GB monthly data usage threshold. If you exceed more than 250 GB, you may receive a call from the Customer Security Assurance ("CSA") team to notify you of excessive use. At that time, we will tell you exactly how much data you used. When we call you, we try to help you identify the source of excessive use and ask you to moderate your usage, which the vast majority of our customers do voluntarily. If you exceed 250GB again within six months of the first contact, your service will be subject to termination and you will not be eligible for either residential or commercial internet service for twelve (12) months. We know from experience that most customers curb their usage after our first call. If your account is terminated, after the twelve (12) month period expires, you may resume service by subscribing to a service plan appropriate to your needs.

They say they will help you identify the reason you went over your cap. "When we call you, we try to help you identify the source of excessive use and ask you to moderate your usage, which the vast majority of our customers do voluntarily." Which they clearly didn't do in this case. This would be acceptable if we had another option for broadband internet, but we don't.
