I am looking for some kind of service / tools, to test provider network in term of latency (ping delay). I know that there are "ping" or looking glass if I am testing it from a single location. But how about if want to test a single IP from several locations ( from all over the world) ?
I found lg.he.net/ but they only allow three locations per test
Is there any thing better than that? free or paid service ? ( I want to use it for my website )
