My point being that building a network which doesn't have more
than an annoying route flap, if /both/ 60 Hudson and 111 8th
avenue are lost, is extremely hard (*) (especially if it has
a transatlantic component). And that's true even if you
have your own fiber.

(*) hard means that it isn't compatible with existing topologies,
and building new ones is expensive.
