NETWORK HOST STATUS
This RFC reports on the status of most Network Hosts from January
3 to January 15.
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. Included here are:
Network
Address Site Computer
------- ---- --------
133 BBN PDP-10 (B)
8* SDC IBM-370/155
13 Case PDP-10
15 Ames/(Paoli) ILLIAC-(B6500)
2) Hosts which are currently intended to be users only. Included here
are the Terminal IMPs, which are presently in the Network (AMES,
MITRE, NBS 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:
Network
Address Site Computer
------- ---- --------
7 Rand IBM-360/65
73 Harvard PDP-1
12 Illinois PDP-11
19 NBS PDP-11
The tables on the next two pages summarize the Host status for
this period.

*The SDC site is currently replacing their IBM 360/67 by an IBM
370/155. This site therefore is temporarily without any permanent
Host on the network, and for this reason was not included in the daily
testing for the preceding two weeks.
**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.

where
D = Dead (Destination Host either dead or inaccessible [due to network
partitioning or local IMP failure] from the BBN Terminal IMP.)
H = 1/2 Open (Destination Host opened a connection but then either
immediately closed it, or did not respond any further.)
O = Open (Destination Host opened a connection and was accessible to users.)
R = Refused (Destination Host returned a CLS to the initial RFC.)
T = Timed out (Destination Host did not complete the ICP and open a
connection within 60 seconds.
*The only service currently offered by the UCLA IBM-360/91 is a Network Job
Service (NETRJS), however, the BBN Terminal IMP is not equipped to test
indicates that NETRJS is also functioning.
#These sites advertise that they may not have their system available at these
times.
