IMP System Announcement

SITE POWER PROBLEMS
   The network has recently been experiencing serious difficulties
   related to the annual problem of more demand for electricity than is
   available during the summer months.  For example:

       During the month of June, between 1/4 and 1/2 of the
       IMP down time was due to site power failure.

       During the weekend of July 15-16, two sites were down
       all weekend due to air-conditioning failure which was
       apparently related to power failures or brownouts.
       This left several sites connected to the rest of the
       net through only one path which, according to Murphy's
       law, eventually failed - leaving nine sites partitioned
       from the remainder.

       On July 18, an underground power transformer supplying
       power to the entire computer room at site 27 failed,
       putting IMP 27 out of action for several hours (anddit
       could easily have been several weeks.)

   Obviously in these cases there is little that either the NCC or the
   site can do to restore service.  We expect these situations to
   continue or even get worse as the summer continues.  Please try to
   restrain your annoyance when these situations arise; we don't like
   them either!
