This RFC reports on the status of most Network Hosts from October 12
to October 22. (Monday, October 11 was Columbus Day.) During these
two weeks, the general status of these Hosts remained as it had been
previously.
The table on the following page summarizes the daily information on
Host status for this period.

RFC 255 October 1971
where
D = Dead (Destination Host either dead or inaccessible [due to
network partitioning or local IMP failure] from the BBN Terminal
IMP.)
R = Refused (Destination Host returned a CLS to the initial RFC.)
T = Timed out (Destination Host did not respond in any way to the
initial RFC, although not dead.)
H = 1/2 Open (Destination Host opened a connection but then
either immediately closed it, or did not respond any further.)
O = Opened (Destination Host opened a connection and was
accessible to user.)
* The UCLA IMB-360/91 currently has Remote Job Service (NETRJS),
but has not implemented a full server Telnet System. The BBN
Terminal IMP is not equipped to test NETRJS however, we are
assuming that receipt of the UCLA explanatory message indicates
that NETRJS is also functioning.
# These sites advertise that they may not have their system
available at these times.
