Here's what I know, and it's not much at the moment.
The web host was telling us that our disk space was full, which is highly improbable. We pay for extra disk space every month, and it's not reasonable to think it's all full up. For example, RN3 ran for about 6 or 7 years, and a full site backup of it is only about 8 or 9 GB. This site has been running for about a year, so it should be nowhere near that. We have, currently, about 100 GB of storage space, and a worst-case estimate would not have more than 1/4 of that space in use.
Once before, when we had similar issues, they told us the same thing, but as it turned out they had misallocated our space, leading to a false report that the space was all used up... but we got that fixed.
Also, the web host has been, for the past couple of weeks, migrating some sites to new servers because of issues they were having with the old servers. I know that one of those servers is located in the UK, but am unsure of where the other one is. I don't know if this site was impacted by that migration or not, and the web host isn't saying.
At one point, the web host claimed the site was up, and posted a screenshot of it to prove it... but when I tried, it was still down, so I sent them a screenshot of the MyBB Error screen, and told them "nice that you can access the site, but this is what the rest of the world is getting."
About 3 hours after that, the site was back up, with so far no explanation.
I did try to do a full-site backup a few days ago. Since the attack on RN3, I've gotten paranoid about that, and so periodically do full site backups and store them locally just in case. When I tried a few days ago, the backups got to 13 bytes and would stop, indicating a "disk full" problem just as the web host reported, but again that is not a condition that should exist. My best guess is that it is a disk space misallocation error that needs to be fixed, perhaps brought on by the migrations in progress, but that's just a guess.
I'm basically just stabbing in the dark at this point, just like everyone else.
