We will migrate one of our mariadb instances to RockyLinux which will affect the puzzle website (http://www.puzzle.ch) and some HAST Services. There will be a scheduled downtime for the Website & the HAST Services during the migration of the database server.
Please be aware that you can't use the website (https://www.puzzle.ch) or the HAST Services on Thursday starting from 18:00 until the end of this maintenance.
