I wish I knew for sure.  I suspect that is the case, but I don't know for sure.
  That's why I said it was a start.  <shrug>

One thing you might try is to do traceroutes to sites in different countries. 
You can watch the response time for the ping before and after the cross-pond
cable, for example.

$ traceroute www.theregister.co.uk

You can see the pond hop at hop #12.  Find sites in various countries, and
you'll have some data.
