Check website ping speed from around the world

I've been dealing with the Great Firewall of China, or at least some sort of traffic blocking over there and it's driving me crazy. In my research for the problems I'm trying to fix I ran across this webpage which some of you may find helpful. http://www.watchmouse.com/en/ping.php allows you to put in a URL or IP address and then will give you ping results from various locations of theirs from around the world.
