+RFC # 376 8 August 1972
+Categories: F, G.3
+Updates: RFC #370
+Obsoletes: None
+
+ NETWORK HOST STATUS
+
+ This RFC reports on the status of most Network Hosts from
+July 31 to August 4.
+
+ Several Hosts are currently excluded from the daily testing
+as they are presently intended to be users only. Included here
+are the Terminal IMPs, which are presently in the Network (AMES,
+MITRE, RADC, NBS, ETAC, USC, GWC, NOAA, SAAC, ARPA, 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
+ 138 Lincoln TSP
+ 12 Illinois PDP-11
+ 19 NBS PDP-11
+ 23 USC IBM-360/44
+
+ The tables on the next two pages summarize the Host status
+for this period.
+
+NOTE: Ellen Westheimer left BBN to return to school on August 4.
+We therefore will discontinue the publication of these summaries.
+It is my understanding that UCLA-NMC is considering the publica-
+tion of similar, although more detailed, survey data in the near
+future; I hope that data will serve in lieu of these reports. In
+addition, of course, MIT-DMCG has had survey information available
+on line for some time (see RFC #308, NIC 9259.)

+*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 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 NETRJS. We are assuming that initial connection to the NETRJS
+ logger indicates that NETRJS is also functioning.
