The success of your site relies not simply on its specific content, but on the overall user experience and the latter could be vastly affected by the network connection to the web server in which the website is hosted. A fantastic site will do no good if, for example, a number of people can surf around it very quick, but the channel capacity is low, so other visitors need to wait and aren't able to access anything, or if everyone is able to reach the site, but the overall network speed is lower, so it takes a minute to open a web page, let alone to load a big image or a video clip. The network capacity is a component which may have a considerable influence on your site, so it's something you must take into consideration when you choose where to host your sites. Higher throughput and access speeds will guarantee fast loading websites and more satisfied site visitors.
