There be mountains in the way, with deserts in between, and not a lot
of people to justify diversity or railroads and highways to run it
Not many carriers have more than one fiber route across Arizona and
New Mexico, especially for the newer high-capacity fibers (i.e. built
this millennium, after the financial excesses of the 90s.)
I'm no longer current on what routes are being used by what carriers,
but if you don't have two routes across northern Arizona ( I-10/I-40,
with restoration routes like Barstow->LasVegas->Flagstaff->Phoenix),
then the next alternative is Barstow->LasVegas->SaltLakeCity->Denver,
at which point some carriers have routes down to Phoenix via Tucumcari
or Amarillo, and the rest are going to go through Dallas, and anybody
who doesn't have the LasVegas->SLC route is going to use
Sacramento->SLC->Denver, possibly also including San Jose, depending
on what routes they've got across California.

So, yeah, instead of the nice short 2200-mile restoration routes you
can use if SF->Seattle fails, cable cuts in the Southwest can be
really long...

Note that this isn't my regular email account - It's still experimental so far.
And Google probably logs and indexes everything you send it.
