the reason cogent is no good sometimes is they have limited peering, and are peered in fewer spots so instead of exiting at a close peering point you have to travel way out. The best example is that when you you are in LA and trying to get to another peer thats also in LA often times you have to go to san jose to get to the peering point which then goes back to LA through the other network. This is what makes latency. 15 milliseconds to go up to san jose plus 15 ms back when you could have peered right to a peering point in LA. If you stay in cogents network they are really fast. When you choose a host, find how many peers they have, ask for ip's in all their networks and trace from multiple sources to all the ip's. If you have any more questions please feel free to icq or email me.
