At about 45 minutes it is interesting history about early computing.
The Computer History Museum has released 21 videos from a 1976 conference.

https://computerhistory.org/playlists/international-research-conference-on-the-history-of-computing/

I’ve only watched the one, and I’m sure the others are interesting as well.

Message-ID: <YqkIvlpQPFq1woQu@minnie.tuhs.org>

All, does anybody know the status of classiccmp.org? It's been down for a
few days and I'm already missing the cctalk list.

If it's a issue of hosting, and someone has Jay West's e-mail address,
then I could host the list on minnie. I've just done the mailman3
upgrade with mailman2 running concurrently to provide old-school list
archives. I'd be happy to give Jay access to the system.

Cheers, Warren

The server is offline. I believe Jay is on the road this week and doesn't
have remote access.

Migration is planned for "soon" but this was not a planned outage.

Ah. I too am missing a "noise" coming from that direction. A noise,
well, a buzz, of bees always repairing their hardware, nothing negative.

I think that it will be interesting to see how much email makes it 
through once services are brought back on line.

I've always retained mail for two weeks before giving up.  Not as may 
people do so for as long any more.

As you might know, when the target does not receive email, sender will
try to send it to backup receiver(s), here:

 $ dig classiccmp.org MX

; <<>> DiG 9.16.27-Debian <<>> classiccmp.org MX
;; global options: +cmd

classiccmp.org.         1799    IN      MX      10 mx1.ezwind.net.

[...]

and from this:

[

https://en.wikipedia.org/wiki/MX_record

]

I infer that the actual date when email will get dumped to /dev/null
depends on settings of relevant mail servers (MTAs) - either sending one
or backup receiver. If there is a way to get those value remotely by
talking to the server, I have not yet dug it up, nor looked.

I assume it might be about two weeks in case of classiccmp and each
email author should be notified when his email fails to reach a
recipient. So, we will see (experiment by doing nothing...),

That's the idea.  At least in an ideal world.  Sadly, I've experienced 
too many ... less than ideal installations.

Those are actually two equal weight peer MXs.  There's nothing 
differentiating one as primary and backup.  The "10" would need to be 
different between the two records.

In an ideal world, messages would never be dumped to /dev/null.  Per RFC 
-- the bible of interoperability on the Internet -- messages should 
never be lost.  Instead, such ultimate undeliverables situations should 
be reported to the (purported) sender.

I'm not aware of anything in the SMTP protocol that is applicable for 
getting such information.  Sometimes it can be inferred by observing 
behavior.

I did receive such a Delivery Status Notification (a.k.a. DSN) from 
mx1.ezwind.net five days after I sent a message to cctalk.

Yep.  Hence "inferred by observing".  ;-)

It seems as if classiccmp.org is now back online.

I received messages from the cctalk mailing list and checked and found 
it online again.

Alas, it seems like classiccmp.org is no good again. This time, when I
open it, some dialog box pops up asking for a word. In the background
below it, there seems to be something like a web panel...
