Network Working Group Ellen Westheimer Request for Comments: 353 BBN NIC #10595 12 June 1972 Categories: F, G.3 Updates: RFC #344 Obsoletes: None

                        NETWORK HOST STATUS
 This RFC reports on the status of most Network Hosts from May 22 to
 June 2.
 No testing was done on Memorial Day, which Massachusetts celebrated
 on May 29.  No testing was done on May 31 and June 1 due to an
 attempt to install the new IMP system.
 Three new terminal IMPs were installed during this interval.  On June
 1, Terminal IMP #155 was installed at Fort Belvoir in Fairfax,
 Virginia; on June 3, Terminal IMP #154 was installed at SAAC (Seismic
 Array Analysis Center) in Alexandria, Virginia; and on June 5,
 Terminal IMP #153 was installed at NOAA (National Oceanic Analysis
 Agency) in Boulder, Colorado.
 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) on a regular basis
     for at least two weeks.  The only Host in this category is the
     PDP-10 at Case (Network address 13).
    2) Hosts which are currently intended to be users only.  Included
     here are the Terminal IMPs, which are presently in the Network
     BBN*).  This category also includes the Network Control Center
 *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.

 computer (Network address 5) which is used solely for gathering
 statistics from the Network.  Finally, included among these Hosts are
 the following:

 Job Service (NETRJS), however, the BBN Terminal IMP is not equipped to
 test NETRJS.  We are assuming that initial connection to the NETRJS
 logger indicates that NETRJS is also functioning.
