We had some downtime yesterday. The computer that has been running the sites, while working fine, was on a dead end path. It was running Ubuntu 18.04 that was 32bit. There is no real upgrade path from there, and moving to 64bit Ubuntu 20.04 proved to be a couple hour endeavor yesterday.
Anyhow, it seems most everything is working fine right now. There are still a couple of backend things that I need to sort out, but the web part seems fine now.
