In 2019 I'm reading one RFC a day in chronological order starting from the very first one. More on this project here. There is a table of contents for all my RFC posts.
RFC-315 is titled “Network host status”. It's authored by Ellen Westheimer of BBN and dated March 8, 1972.
The technical content
This is another report from BBN on the status of various ARPANET hosts in the same series as RFC-306, RFC-298, RFC-288, RFC-287, RFC-267, RFC-266, RFC-255, RFC-252, RFC-235, and RFC-240.
The numbers, from February 14 to February 25:
- 77 dead
- 61 open
- 15 half open
- 9 timed out
We are at about 45% online status for the longest-running ARPANET servers, and 37% online overall.
