+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:

+ 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.
