SpeedTest.net is "a general use broadband connection testing site with many geographically dispersed servers to test against. Here we plan to demonstrate and beta test our latest Ookla Speed Test creations such as latency, jitter, client location and distance to server calculations. Test your connection anytime and even store your results for future reference." If nothing else, it's cool to watch for those that miss watching the little blocks move around while defragging their hard drive. (Sorry, it only takes about 30 seconds to complete a test.)
