It's been a long time coming but
wansecurity.com has finally come on
line; they are hosting the 'other' files (includes goodies like Picture
of the Year collections, pageview and other stats), as well as MediaWiki
tarballs and the historical XML archives, at present. we're talking

See:

for the mirror,
http://www.wansec.com/
for the company and
http://www.wansec.com/Services/RemoteBackup
for the service which they are donating.
