Bandwidth or "Data Transfer"  Each time a visitor to your web site makes a request for a web page to load our server sends these images and web page to the clients browser. The total value send it recorded and that is what is referred to as data transfer or bandwidth. We do not shut your site down when it becomes popular. Other hosts approach seems a bit like shutting off your electric, or cell phone before you even see a bill. We do bill at $3.75 per gig for every gig over what is included in your account. This fee is so marginal that one would question what all the talk is about. If you are making money off your site this would generally indicate you are making more money. We give every web site the burstable bandwidth it needs when it is popular.
