                              SITE STATUS

   Beginning with this RFC, BBN will report on the status of most
   Network Hosts approximately once every two weeks.  The information
   for these reports will be gained from talking to people at each site,
   and from experimental "data".  These data will be the results of
   daily attempts to log into each of the Hosts which might be
   accessible to a Network user; the attempts will have been made from
   the BBN prototype Terminal IMP at a random time each weekday.

   Several Hosts are currently excluded from the daily testing.  These
   Hosts fall into two categories:

      1)  Hosts which are not expected to be functioning on the Network
      as servers (available for use from other sites) for at least a
      month.  Included here are:

            Network             Site              Computer
            Address

             71                 Rand              PDP-10
             74                 Lincoln           TX2
             11                 Stanford          PDP-10
             13                 Case              PDP-10
             14                 Carnegie          PDP-10
             15                 Paoli             B6500

      2)  Hosts which are currently intended to be users only.  Included
      here are the Terminal IMPs presently in the Network (AMES, MITRE,
      and BBN*).  This category also includes the Network Control Center
      computer (Network Address 5) which is used solely for gathering
      statistics from the Network.  Finally, included among these Hosts
      are the following:











RFC 235                       Site Status                 September 1971


            Network              Site               Computer
            Address

               7                 Rand               IBM-360
              73                 Harvard            PDP-1
              12                 Illinois           PDP-11

   The tables on the next two pages condense the information on Host
   status for September 13 through September 24.

________________
* The BBN Terminal IMP (Network Address 158) is a prototype, and as such
is frequently not connected to the Network, but being used to refine and
debug the Terminal IMP programs.

      * The UCLA IBM-360 is at the moment only able to handle Remote Job
      Service.  BBN is not equipped to test this, but is assuming that
      receipt of their canned message indicates that RJS is also
      functioning.
