RFC-326 is titled “Network Host Status”. It's authored by Ellen Westheimer of BBN and dated April 3, 1972.
The technical content
This is another report from BBN on the status of various ARPANET hosts in the same series as 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 March 13 to March 24:
- 84 dead
- 81 open
- 21 half open
- 4 timed out
We are at about 66% online status for the longest-running ARPANET servers, and 42% online overall. Still showing an upward trend in availability, at least on the core servers.
