So with your key peers you talk to them and find out, but 
I don't see how this is any different if you have a private 
interconnect. Just because you have say a STM-1 into another peer
doesn't mean they have the STM-1 to carry the traffic out, given
your example below I'd say its even more unlikely.

Key ones, yes.

But your point on public versus private doesn't alter those facts.
