Building multiple diverse paths and monitoring for fiber cuts is not hard. Having 2 fiber paths is insufficient for even only moderately important workloads at a tech company. Overlapping fiber cuts happen. For something with significant economic and safety impact this is just crazy.
Sometimes the level of incompetence / lack of care in organizations like this astounds me. I understand issues like this can be complicated and systemic but it honestly makes me think very poorly of the technologists building these systems in government.

I imagine there will be some soul-searching over that. Nothing I've ever seen or experienced with FAA indicates a lack of care; the parsimonious explanation is almost always that people who care a great deal are working within complex systems that don't always have a consistent or externally legible set of priorities. Or more intuitively, the failures we see are the "acceptable" ones versus the unacceptable ones (like planes falling out of the sky).
