RFC-332 is titled “Network Host Status”. It's authored by Ellen Westheimer of BBN and dated April 25, 1972.
The technical content
This is another report from BBN on the status of various ARPANET hosts in the same series as RFC-330, RFC-326, RFC-319, RFC-315, RFC-306, RFC-298, RFC-288, RFC-287, RFC-267, RFC-266, RFC-255, RFC-252, RFC-235, and RFC-240.
The numbers, from April 10 to April 21:
- 76 dead
- 84 open
- 9 half open
- 16 timed out
- 1 refused
- 4 full/busy
We are at about 52% online status for the longest-running ARPANET servers, and 44% online overall. This is the first time (I think) we see a “full” status on a server, which basically means there are too many people already connected to the server so it closed the connection when the measurement was taken.
