If you think of us a rural/urban networking topology, most of the San Juan
metroplex is fine. Within that area are pockets without power, water,
Internet.
Then in most of the larger cities the same, now we switch immediately to a
rural model. Spokes of functionality extending into smaller pueblos. If the
spoke you live on is with out a service, then everyone down stream is
usually without that service.
It turns out that the utilities were laid out in daisy chains. Many the
chains that are completely inoperational may take years for the
infrastructure to be rebuilt again.
