Some time ago they killed all the hosted sites on the planet* sites. Now Fileplanet which they forced their hosted sites to use for downloads. Expletives!
By the way, I mirrored the forumplanet forums a while ago: http://archive.org/details/Forumplanet.gamespy.comArchive

Eh, about forumplanet… http://forumplanet.gamespy.com/ is redirecting to http://www.ign.com/boards/ now. I could not find any of the old Quake boards.
http://www.ign.com/boards/forums/diablo.5218/ suggests they just moved them all though. Morons.
If it’s any help (probably redundant), I did a partial mirror of planetquake many years ago. http://taniwha.org/~bill/games.txt.gz a list of what I’ve got readily accessible.
I will get back to you.

One year later, we are finally truly getting close to completion.
All files are now uploaded to IA. Stay tuned for a user-interface.
~120 000 public files, 9.5TB
~200-300 000 not public as those are mixed with private files, ~2TB or something
I am now finally working on a frontend. Very WIP but functional https://www.quaddicted.com/stuff/temp/fileplanet.php?filename=quake
Not fancy, but you can download fine.
If someone wants to collaborate, please shout. It’s php & sqlite3. Great features to have would be a realtime search box and pagination. I have more metadata, screenshots etc, which I will join later. I will probably also properly restore the timestamps, noticed the “23:00:00” just now. I have them accurate to the minute.
Some more work on it, directory browsing and detail pages where we have details.

Still very WIP, so keep it to yourself.
13 years later it is time to drop PHP from the server though.
I played with some unethical LLM vibe coding to convert it to HTML+JS with sql.js but realised that I have no idea how to do a security review of the result. So instead, it's bye-bye to this search interface for now.
To make sure it is not lost, I enabled listing and .php file download for the directory: https://www.quaddicted.com/stuff/fileplanet/
There are some older databases and other files too, sorry for the mess.
It would be ace if someone would host this elsewhere for us archivists.
If someone wants to look at the horrible but working-for-the-user LLM output of the conversion to check for security issues OR convert it themselves so I could host it, message me. <3
