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-240 is titled “Site Status”. It's authored by Alex McKenzie of BBN and dated September 30, 1971.
The technical content
McKenzie is issuing a correction to RFC-235, which published statistics about the the various sites around the network. He apologizes profusely in the opening for “
any embarassment this may have caused to anyone associated with the Network”.
The new aggregate stats are, by my count:
- 57 dead (+1 from prior)
- 34 open (+1 from prior)
- 16 timed out (-1 from prior)
- 9 half open (-1 from prior)
- 4 refused
These stats are really not very different from the ones reported in RFC-235! Specifically the discrepancies are:
- BBN was fully open rather than half open for one test
- MIT(DM) is dead at one point rather than half open
I'm not sure why McKenzie's apologies are so profuse!
