You can have all the redundant power, high availability hardware, and
ultra-Robocop security going, and still have crashes: so far as I
know, _nobody_ makes perfectly reliable hardware, and the harder you
push it, the more likely you are to find trouble. And certainly,
when you have a surprise outage because the CPU where the kernel
happened to be burned itself up, an extra hour or two offline while
you do fsck is liable to make you cry out variations of those four
letters more than once. :-/
