Every system, mechanical or electrical, is designed to
require breaks. When a system is being worked out, when it looks like the
system is being overused, when there's overheating, when it begins to show
signs of malfunctioning - then a break is needed.
I'm sure you must’ve gotten one of those messages from your
bank stating that “the online banking system is down and going through a
routine check”. At such times, it might not be convenient for the users, but
its expedient it happens so that a more terrible thing doesn’t occur. When
using a computer system, we would say it’s getting hot and let it rest for a
while. A vehicle driving for so long deserves some form of rest after getting
on with one long distance journey, or the other, from one place to another.
