We were running along just great, I was migrating all sorts of site, was totally sold on the panel etc, then the bottom drops out. Mysql shows it's still running but nothing is able to connect. Every one of our sites on this server went down. I restarted, nothing. I reinstalled, noting. MariaDB 10.3. Had to take the day yesterday and migrate everything off of this server, not what I wanted to do but WTF?
