    No, this is very helpful. We just turned up AdventNet's Net Flow 
Analyzer for this customer's two production cisco 7507s and we should be 
able to see where the European customers are very shortly. It is good to 
know that Cogent is a decent choice for this job - we've seen not so 
positive stuff about them here in the past. If we can narrow things down 
to Cogent and Level 3 right away that is a good place to start. Someone 
sent me to peeringdb.com and it looks like I have plenty of places to 
choose from in London.
