bandwith charges (Score 1)

If the isp is only responsible for the leased line and routing and the customer is responsible for the server and content then the customer gets charged for the bandwidth. If the isp is responsible for the server (say they provide the web space for my companies page) then they should eat the cost due to the improper management of the server. I would even go so far as to say that any customer that fails to have their server properly maintained and patched should also have a penalty fee. Ultimately the isp has to deal with the bandwidth usage.
