Is there a (free?) service to test website speeds which simulates concurrent users from different parts of a/the country? The handful I've looked at seem to test from a single location, which doesn't give an accurate result for real world use.
I work for a newspaper. Most of our hits come from within our region. But, when we pick up or generate nationally significant content, we see a spike in national hits. I need to be able to test our new site in development from geographically diverse locations. I'm more of a network and hardware guy than web, so I'm coming at this from a network hops, differing bandwidth, and differing ISP point of view.
