nixos.wiki was the primary wiki before NixOS really had an official one. Now there is the official wiki.nixos.org and the NixOS foundation asked the nixos.wiki maintainer to cooperate on the new wiki but they refused. Now there are multiple problems[1] with nixos.wiki and the maintainer in unresponsive so although unfortunately it's ranked higher in search results, in my experience you'll get better information on the official wiki.

I went to see what the problems were for myself. While I wouldn't run my own sure that way, I was expecting something more serious to justify a migration. I think having the primary wiki within the project is a good idea generally. It does feel like the problems below are just minor annoyances though.

Why is there a new wiki? What is with nixos.wiki?

The old wiki at nixos.wiki has several problems:

    Many components (mediawiki, php, icu) are severely outdated.
        MediaWiki 1.29 (EOL 2018), now 1.35 (EOL 2023-12)
        PHP 7.3.33 (EOL 2021-12)
        ICU 64.2
    Cloudflare DDOS protection makes wiki edits fail sometimes.
    There is no WYSIWYG editor.
    The wiki infrastructure, which was supposed to be made public after launch, never ended-up being made public

I suspect both of these are a bigger deal to the Nix community than perhaps to the average group.

Ah, too bad the maintainer is unresponsive. If they don't plan to work on it, they'd do a huge service to community by adding permanent redirects to wiki.nixos.org and maybe canonical links.
