Click Tacoma has a cap too
Click Tacoma has an AUP of capping residential use to 250 GB and business use to 300 GB. It does not look like they have upgraded to DOCSIS 3.0 which is able to handle a lot higher usage. I wouldn't be surprised once Comcast is fully upgraded that they will increase or remove their cap as well. Comcast runs Fancast through their Xfinity services which they will want to people to use in conjunction with their service. I suspect they have to continue having the caps until the upgrades are complete and in case a node had every subscriber trying to heavily seed P2P causing congestion problems. Hopefully AT&T, Frontier, Charter, Bell, and Rogers can see the light and stop overcharging their customers on extreme overage charges.
