Well, it's either London or Amsterdam..:-) It I look at the old KQ 
network and what I know of the larger providers we peered with (so this 
information is around a year old) I would say that well over 50% of 
European traffic went through private peers. Of those peers I would say 
that between 60-75% went through London or Amsterdam. So yes, we did 
see a lot of traffic taking detours when heading for a peering.

KQ might still not be a typical provider as we had such a large 
percentage of the transit market in Europe. This meant that we had very 
few problems with this. We had more problems with non-customers and 
other US based carriers traffic taking detours in their network to get 
to/from us.
