Hello again! I noticed that the Org documentation server gives 404 Not Found for a large number of links published all over the internet because (1) it parses URLs case-sensitively and (2) the case has changed at some point. I stumble upon such 404s errors daily. See, for instance, the link to Column Groups documentation in this Stack Overflow answer:

I know that Org does not compete for popularity, but for the people getting familiar with it, this issue might cause a lot of headaches for no good reason.
