Simple. Slashdot = www.slashdot.org. If you don't know it, you should (if you
are on any Debian mailing list. ;) )
Slashdot effect: an article gets posted on Slashdot with a URL. Traffic to
that URL then does this:
H | .--------------.
I | | --------
T | |
S |------
+------------------------------
^ Time ->
article posted
Forgive me if this is an approximate logorithmic scale. ;)
ie: MASSIVE PEAKS. I think Tridge (Andrew Tridgewell) has a TShirt from the
LinuxCare labs web site when they got slashdotted with the above style graph
on it when they got mentioned.
As far as adaptive caching and mirroring; they probably just have a squid
accelerator set up. Any inbound requests are proxied to the main mirror they
are replicating, and cached...
Though there are other techniques, some of which Simon Holmes discussed
at Linux.conf.au in Sydney in January. Plus various other cool things can
be done with hacking FTP daemons if one so desires, and taking advantage
of the FTP protocol...
Hope this helps.
Yours,
James
