I had assumed that this file would be, if not versioned, at least
immutable, due to the filename looking like a hash of some sort. But it
was changed upstream recently. So, I'd need to provide an immutable
source for this as well.

I wonder if it would be better to take another approach here. I don't
want to have to create a new archive.org upload every time something
changes in the data set, which could be quite often given the scope of
information it includes.
