Some tech details,

MySQL database restarted by itself for some reason, not sure why yet.

2021-02-03T06:37:18.935293Z 0 [System] [MY-013172] [Server] Received SHUTDOWN from user . Shutting down mysqld (Version: 8.0.22-0ubuntu0.20.04.3).

Unfortunately, apparmor configuration, which seems to manage which files the mysql user has access to, was missing the allow write rules to the mysql datadir, which prevented the database to start.
