Nice Speed Test Site
The German router producer AVM - IMHO making the world best routers - has a nice speed test site. It does not only include the usual upload and download tests and ping, but also jitter and packet loss. For those who don't live in Germany, it can still help to check how good e.g. your overseas connection is. If you're interested in those routers, google for AVM Fritz Box.
