Stuff disapppearing in incoming/

[odd]

Hello again.

I was just curious as to if there is another place than the regular
incoming/ mirrors, to fetch the
"experimental" ppc stuff, like the pmacinstall-xx, and the
"(base2_2.1.tar.gz)" - because I can't seem to find it on the mirrors I've
got. FTPSearch finds them, but the actual files aren't there - so I figure
that indicates that files get "outdated" after a while?
