Yes it is already changing. But as far as I can see, Global
SprintLink represents the old US-centric model: GSL is the
international arm of SprintLink and essentially sells bandwidth
into the States. C&W is setting itself up as a global backbone
provider.
GSL offers both IPL and POP accesses, and participates local-exchange
within country/reginal POPs. US-centric model is juct matter of economy
and tariff between countries. If someone is willing to pay more to run a DS-3
from Taiwan to Japan instead, I am sure there is no reason for GSL to reject
the order.
