You sure the cpu on the teleglobe router in the path isn't just pegged?
If the rtt for the whole path is 400ms but one hop in the middles shows
1100ms you're probably measuring the performance of the scheduler in the
OS the router is running not rtt to and from that router, packets going
through it rather than to it likely take a different path through the box.
Of course if the customer's rtt is 1100+ ms then sure there's probably
serious congestion on one of those links.
