RFC 353
Network host status
NETWORK HOST STATUS 💖
Network Working Group 🎀 Request for Comments: 353 🦋 (NIC #10595) Author: Ellen Westheimer, BBN 🧚 Date: 12 June 1972 🍓 Categories: F, G.3 ✨ Updates: RFC #344 ⭐ Obsoletes: None 💅
Overview 🌸
Okay bestie, this RFC is a status check on most of the Network Hosts from May 22 to June 2. 👀 Ellen's basically the queen of keeping receipts on who's online and who's ghosting. 💀
No testing happened on Memorial Day, which Massachusetts celebrated on May 29. 🇺🇸 No testing happened on May 31 and June 1 either, because they were trying to install the new IMP system. 😭
Terminal IMPs Installed 🔥
Three new terminal IMPs got installed during this stretch, and they're giving main character energy:
- 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. 🌈
- On June 5, Terminal IMP #153 was installed at NOAA (National Oceanic Analysis Agency) in Boulder, Colorado. 🏔️
Hosts Excluded From Daily Testing 🙈
Some Hosts are not in the daily testing lineup rn. They fall into two groups:
- Hosts that aren't expected to be working 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 group is the PDP-10 at Case (Network address 13). 💜
- Hosts that are currently meant to be users only. This group includes the Terminal IMPs that are presently on the Network (AMES, MITRE, NBS, ETAC, USC, GWC, NOAA, SAAC, BELVOIR, and BBN*). It also includes the Network Control Center computer (Network address 5), which is used solely for gathering statistics from the Network. Finally, these Hosts are also in this group:
Network
Address Site Computer
------- ---- --------
7 Rand IBM-360/65
73 Harvard PDP-1
12 Illinois PDP-11
19 NBS PDP-11
23 USC IBM-360/44Footnote *: The BBN Terminal IMP (Network Address 158) is a prototype, so it's frequently not connected to the Network. It's being used to refine and debug the Terminal IMP programs instead. 🛠️

*Host not included in daily testing
#The NMC is a research site and would like to have prior arrangement
with each user.Footnote *: The only service the UCLA IBM-360/91 currently offers is a Network Job Service (NETRJS). The BBN Terminal IMP isn't equipped to test NETRJS, so we're assuming that a successful initial connection to the NETRJS logger means NETRJS is working too. 🤞

Here's what all the letters mean, where:
D = Dead (Destination Host either dead or inaccessible [due to
network partitioning or local IMP failure] from the BBN Terminal
IMP.)
F = Full (Destination Host opened a connection, informed user that
all Network ports were in use, and immediately closed the
connection.)
H = 1/2 Open (Destination Host opened a connection but then either
immediately closed it, or did not respond any further.)
O = Open (Destination opened a connection and was accessible to us.
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.)*Host not included in daily testing. ✨ #These sites advertise that they may not have their system available at these times.
