When an ISP considers that you're using up a lot of bandwidth, they redirect your IP to a 'cached' proxy. They may have only one, or multiple amounts of these servers, but the idea is, that instead of you using their precious bandwidth to load up websites, the proxy instead sends you a 'cached' version of that website.
