today reminded me of tilde.town, which is a publicly accessible

Not quite a thousand users logged in simultaneously, but half that. If
one counts the number of processes associated with pseudoterminals,
it's more (I guess a lot of users are running tmux and/or screen).
The system is also surprisingly modest: 6 cores, 16GiB of RAM and
about 1TB of storage.
It's surprisingly zippy.

I don't know if a thousand users ever logged in there at one time, but
they do tend to have a lot of simultaneous logins. [bumping to COFF]

The
evolution of platforms like laptops to becoming full distributed systems continues.
The wheel of reincarnation spins counter clockwise -- or sideways?
About a year ago, I ran across an email written a decade or more prior
on some mainframe mailing list where someone wrote something like,
"wow! It just occurred to me that my Athlon machine is faster than the
ES/3090-600J I used in 1989!" Some guy responded angrily, rising to
the wounded honor of IBM, raving about how preposterous this was
because the mainframe could handle a thousand users logged in at one
time and there's no way this Linux box could ever do that. For that matter, a
thousand users probably _could_ telnet into the Athlon system. With
telnet in line mode, it'd probably even be decently responsive.
sdf.org (formerly sdf.lonestar.org) comes to mind...
