ISP Throttling Test for BitTorrent and Usenet Traffic
Do you have suspicions that your ISP may be throttling (a.k.a. traffic shaping) some of your Internet traffic? It's easy to tell if your ISP is blocking something, such as BitTorrent traffic, since nothing will get through, but it is more difficult to tell whether they are just restricting your download/upload speeds. That's where the free Glasnost service comes into play.
