Keys are now rotated, and I think I've learned a few security lessons from this (setting up the Seaweed server like almost a decade ago, I'm amazed it lasted this long without getting fucked... made some really bad decisions back then).
Once the server is re-imaged, I can get to work on reinstalling and restoring the backups. But that's going to have to be for another day.
For now, goodnight fedi.
