down 1. adj. 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}.
