Wouldn't they be over at the Internet Archive.org?

Not for a while. The norobots file they used has a specific flag in it that tells the internet archive to delete it's copy of the content.

Hmm, I thought the whole point of an archive was that it was read only, you couldn't delete...

Yeah, me too. I guess the internet archive still has to conform to ID and copyright law though - if someone asks for something they own the rights to to be removed, they have to remove it.

IIRC it's back up there now they've changed their mind, but it does raise an interesting question about how much of a point there is to the archive..
