That is one long protect path. Yikes.
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 along. 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 I'm no longer current on what routes are being used by what carriers, but if you don't have two routes across northern Arizona ( I-10/I-40, with restoration routes like Barstow-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... -- ---- Thanks; Bill 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.
