yes - something changed with my ISP about two weeks ago and asking
them got no useful information other than that they're using ProFTPD.

See

This should work:

ftp://ftp.invisible-island.net/pub/vile/current/vile-9.8s.tgz...Failed
                               ^^^

It's not handling the symbolic links used to make "/pub/vile" look like
"/vile", etc.  I added those symlinks at the top-level in 2007
(last rebuilt in 2013) to cover up a previous change they made.

no - I think the problem is that the way ProFTPD's handling symlinks
either changed due to an upgrade, or someone modified the configuration.
Perhaps that involves permissions, but only within ProFTPD (the website's
still the same).

Either way, it's not visible to me: the configuration is outside the
container that my website runs in.  (On the plus side, I might
be able to set up ProFTPD on a local machine and see how they might
have broken it, to advise...).

actually the person who pointed out the problem to me was trying
to use wget - that didn't work, and nor do any of my browsers.

Using an explicit "/pub" should work for some time :-)
