I noticed that many old tutorials disappeared.
For example, I see the link in the API description, but it doesn’t work anymore: https://doc.babylonjs.com/how_to/playing_sounds_and_music#creating-a-spatial-3d-sound.
I am particularly interested in distanceModel parameter.
Also, the link to the doc on the main https://www.babylonjs.com page is kind of broken.

Thanks a lot. I am going to deal with all of the redirect issues tomorrow. Until then:
It will be addressed after this PR is merged - Fix redirects in code doc by RaananW · Pull Request #13228 · BabylonJS/Babylon.js · GitHub
Thanks a lot for reporting!

Will such links have a 301 redirect?
Another thing: https://doc.babylonjs.com/search?q=SceneLoader. Clicking on the first result (API reference) gives “Page Not found…”.
Not sure it is related but thanks a lot for reporting @splash27 !!! I bet @RaananW will sort it in less time it took me writing this answer
interesting. this issue was already fixed. it might require reindexing the search index. i’ll take care of that!
Thanks a lot.
They should be. However, we are limited in the number of 301 redirects we can offer (server limitations set by vercel). i’ll see if we can increase it to support everything. If not, I will implement an internal redirect to the few URLs that are not redirected (which are probably 5-6 years old)
