The Herd Of Kittens Helps with Paws and Whiskers

Aside from a variety of web sites (by far the most accessible part of The Herd) there are other tools and services that get attention from time to time.

OpenAFS cell
/afs/thok.org is used to share data among known parties, using Kerberos for identification. Roughly 200G of storage, which isn't entirely devoted to kitten pictures.
Image Server
www-images.thok.org will shortly be the "bulk image" server, to allow seperate experiments with clever storage tricks, and possible future offloading and mirroring.
DNS
ns1..ns3.thok.org provide nameservice for a moderate collection of domains; nothing especially clever, but we do provide secondary nameservices for friends and colleagues who don't need actual support.
Operational Platforms
Debian GNU/Linux on x86 and sparc; Solaris 8 on sparc.
Near-operational Platforms
With some effort, we can boot "Research Institute OSF/1 1.2" on a DECmips, sunos-3-based X-kernel on Sun 3/50, some X terminals, DOS 3.11, CP/M 86, TurboDOS, and probably others.
Cruft Platforms
In the hope of running them again someday, we have accumulated Sun 3 (68k), HP 7xx (hppa), HP 3xx (68k), DECstation (mips), TRS-80 (z80), VAX (cvax), and other uncataloged hardware.
Media
DVD-R, CD-R, Exabyte tape, Ecrix tape, Zip, Jaz, Orb, 3.5" floppy, 5.25" floppy, and even 8" floppy for a sufficiently good (or interesting) cause.
