It's was super strange what happened, /u/surreal and I figured out that a backup (snapshot) I made of the site the other day somehow got seen by tor as the de-facto raddle site, and the onion started linking to the backup instead, which is on another server and was non reachable via clearnet.
It's back up and running now:

Big thanks to surreal for spending all their sunday on this.

As u/surreal gets more familiarized with the setup these minor issues will be resolved much quicker. Are you using a host provided backup solution? Personally, considering on Linux everything exists at the file level, why not just set up a cronjob to fire a bash script using rsync for daily backups for seven days, one weekly, and one monthly, of all necessary configs, web server, db, and site level files?
