Anecdotage is, I suppose, innocuous; but it would be helpful to make some distinctions, in particular one between hardware failures and system failures.
Hardware failures that are recovered from are moderately frequent, as everyone who has had occasion to look at SYS1.LOGREC outputs presumably knows. The merit of z/OS and its predecessors is that most such failures are recovered from without system loss. The system continues to be available and to do useful work. The hardware is indeed very reliable, but the machinery for detecting and recovering from hardware [and some software] errors makes an equally important contribution to system availability.
