There are two ways this could work. Either the network basically functions as
its own ISP, and it tries to attract traffic as close to the origin as
possible, or it tries to keep the long distance lines free for private
traffic and has ISPs transport the traffic to as close to the destination as
possible.

In the first case, they would use a globally visible PI address range and
announce a single prefix everywhere in the world. In the second case, they
would get a number of smaller regionally aggregatable ranges and use them in
the appropriate regions.
