In 2007, John Goerzen scraped every gopher site he could find (gopher was a menu-driven text-only precursor to the Web; I got my first online gig programming gopher sites). He saved 780,000 documents, totalling 40GB. Today, most of this is offline, so he's making the entire archive available as a .torrent file; the compressed data is only 15GB. Wanna host the entire history of a medium? Here's your chance!
There are some plans to potentially host this archive publicly in the manner of archive.org; we'll have to wait and see if anything comes of it.
Finally, I have tried to find a place willing to be a permanent host of this data, and to date have struck out. If anybody knows of such a place, please get in touch. I regret that so many Gopher sites disappeared before 2007, but life is what it is, and this is the best snapshot of the old Gopherspace that I'm aware of and would like to make sure that this piece of history is preserved.
