down

Not operating. The up escalator is down is considered a humorous thing to
say (unless of course you were expecting to use it), and The elevator is
down always means The elevator isn't working and never refers to what floor
the elevator is on. With respect to computers, this term has passed into the
mainstream; the extension to other kinds of machine is still confined to
techies (e.g. boiler mechanics may speak of a boiler being down). 2. go down
vi. To stop functioning; usually said of the system. The message from the
console that every hacker hates to hear from the operator is System going
down in 5 minutes. 3. take down , bring down vt. To deactivate purposely,
usually for repair work or PM. I'm taking the system down to work on that
bug in the tape drive. Occasionally one hears the word down by itself used
as a verb in this vt. sense. See crash ; oppose up.
