Greetings from Maui!
tldr: upgrade your Sword apps to always use https instead of http

While technically any network acess other than anonymous FTP support
is optionally supported only with a build dep, in reality there is no
need to support anything other than HTTPS. Every Linux distribution,
and Windows build of note has libcurl, the Brew version is also built
against it, and the HTTP(S) support was added because mobile often
blocks FTP.
So you're basically completely safe.
Awesome!
As many of you are probably aware, the last week was not a model
of reliability for the eBible.org repository, or for the rest of
the eBible.org site. On the 19th of February, the eBible.org
server hardware failed. Exactly what failure, I don't know,
because it was in a data center over 4,000 miles from my house. I
just knew that it wouldn't talk to me in any of the 3 ways I can
normally access the leased dedicated server. No worries, because I
have a fast backup, right? I allocated a new dedicated server
from the same company (Ionos) and attempted to restore from a
backup. That failed with about 80 error messages. Next plan:
restore from a mirror image of the server in my home office. That
actually worked, but it took more than 3 days to get all of the
data there (about 300 GBytes), plus time to get all of the
configuration right. In the mean time, my other leased server (the
one that didn't crash, hosting 24 other sites) gave early warning
signs that it was not going to be in service much longer. Then
everything worked except that I forgot a couple of tweaks I had to
do to make the ftp server compatible with Sword. I fixed that, and
things were still not OK. EBible.org availability kept going up
and down like a yo-yo, mostly because the remote control software
I was using was not designed to handle multiple IP addresses per
server and anonymous ftp sites. Also, the cost of allocating
multiple IP v4 addresses has gone up. Anonymous ftp is pretty much
obsolete. I will be dropping it, but slowly.
A Herculean effort, but I'm glad for you that your recovery was
successful! I'm curious why you need 4 separate addresses? What is the
need, there?
So far, I have been using Plesk to set up virtual hosts. I have 25 sites
(and some aliases for those), some of which are much more important than
others. Plesk lets me share one IP address with all sites except any
site that has an anonymous ftp service associated with it. The only site
I have that has an anonymous ftp service associated with it, of course,
is the ftp.eBible.org Sword repository. So I had to assign 2 IP version
4 addresses to the server. For a long time, I was running 2 servers with
every site on them for redundancy. I had stopped doing that because the
sites grew too large for one of the servers I was renting, and I thought
I had a workable fast backup/restore plan, unlike when I had extremely
slow and expensive Internet in Papua New Guinea. (I have some serious
space in audio and video Bibles.) So that is 2 servers x 2 IP addresses
= 4 IP addresses. But that configuration was unstable, so I went to just
one IP address per server by fighting my old ally, Plesk, using manual
ProFTP configuration (and a cron job to slap my configuration back
whenever Plesk rewrites it). That is not a really good long-term
solution, though.

Would you like a hand building up some DR or deployment automation so
you can avoid needing to remember settings? IT automation is one of my
primary skillsets, so if you'd like any sort of help setting it up,
let me know. For instance, it's not too hard to put together
automation scripts to run on a provisioned box to stand up the web
server, ftp server, etc so that you don't need to manually edit files
and the like.
That would be useful. That could be a way to escape my dependence on and
fight with Plesk.
Alternatively, have you considered an alternative way to host the
data? You could probably build a Container image with all the files in
it and host that on something like Amazon Container Service or any of
the many cloud Kubernetes hosts around. A container image would also
make it easy for someone to grab the whole collection and make it
available in an offline context the way they can with the old CD
images Troy used to distribute.
I have looked at alternatives in the past, but it may be worth looking
again. When I last looked, AWS was more expensive at my traffic levels
and site counts than using a rented dedicated server. Another
alternative might be hosting at my house when (if?) Hawaiian Telephone
makes good on its promise to bring fiber Internet to my neighborhood.
(It is actually available about a half mile away, right now, but I
haven't seen them working on it around here.)
Or even put the files into an object storage container if you're
dedicated to eliminating FTP access eventually. With just a small
shell script you can push the needed files and their indexes into an
S3, Ceph, etc object storage service and then you wouldn't need to run
a dedicated server with them to manage uptime. All of those services
offer ways to expose the files over HTTPS.
As I said on Facebook, I'm happy to lend a hand if there's anything I
can do to help smooth your infrastructure! I can even host an
emergency mirror if need be, as I have pretty reliable Internet and
electric when my neighbors don't drive into the electric poles. This
year I'm dedicating some of my time to working on home electric backups!
Thank you, Greg. I may take you up on that...
