What happened to do not trust anyone? Create your own resiliency by being multihomed to as many transits you can afford.
Re-read what David Hubbard said:
unacceptable period of time (many hours). Iâm learning that the entire market is served by just two fiber routes, through cities hundreds of miles away in either direction. So, basically two fiber cuts, potentially 1000+ miles apart, takes the entire region down.
If in fact there's only two fiber conduit approaches to the area, he's basically stuck no matter how many companies sell him bandwidth in those two conduits. He can contract with 8 companies to have 4 paths through each conduit, and 2 cable cuts *still* leave him dead in the water. (Bonus points for estimating the chances that at least one of those 8 companies will do one or more of the following: (a) not knowing which conduit the path will be in, (b) actively lie about the conduit in order to seal the deal, or (c) re-provision the path several weeks later into the other conduit....) And he probably doesn't have the budget to dig a third trench several hundred miles to a third city...
