Incredible story: In 1971, a tiny bug in AT&T’s switching software caused a cascading failure that took down nearly all long-distance calling in the US. The entire system collapsed because one switch sent a malformed signal and every other switch copied the same failure. Wild early example of distributed-system fragility.
