You are now about to witness the strength of street knowledge. The hard truth is that all systems fail. Codes often written with the assumption that failure of the underlying systems is if not impossible, at least very unusual and probably should result in some manual intervention. But failure and slowdowns, which are as much of a threat as outages, are common.
