Whoever maintains the docbot irc thingy needs to update some URLs by
the sounds of it.

Not easily, if at all. The documentation is dynamically generated from
a database on the master server, which certainly doesn't know what
pages might have been present in previous releases, at least without
trawling through them all and trying to figure it out.

The frontend servers that you actually get the pages from are all
static servers that just serve the pre-generated HTML. They have no
way of dynamically generating a 404 page.
