Iran breaks their communications infrastructure into pseudo-zones. You can
easily pinpoint a few choke points and surgically remove them from the
Internet.

This is the case for many countries. Sometimes the infrastructure is so
hierarchically designed (likely for surveillance purposes) that you could
literally watch their bgp advertisements and potentially draw conclusions
about things "other than" Internet activity.
