Nice ISP's will put speed test software on their backbone so you can 
test the speed of your circuit to the backbone.

Remember that the speed your provider quotes you is probably the full 
throughput of the circuit. Some circuits, such as DSL ones, will read up 
to 15% slower due to ATM circuit overhead.
