I have been witness to N+1 HUMAN failures but never a N+1 hardware failure or system/design failure that warranted questioning the need for N+2. Usually your N+1 failure is (as already referenced) pasting in a bad config that gets replicated or something like that. Not saying the hardware is perfect. It's just that I haven't personally seen a full blown failure like that without human help.
