Network Working Group E. Westheimer Request for Comments: 235 BBN NIC: 7652 September 27, 1971 Obsoletes: None Updates: None

                            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:

            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.

    network partitioning or local IMP failure from the BBN Terminal
    IMP)

    initial RFC, although not dead.)
    1/2 0 = 1/2 Open. (Destination Host opened a connection but then

    0 = Open. (Destination Host opened a connection and was accessible
    to users.
  • 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.
