Moodle was not accessible again today, February 5, 2025, between 13:15. and 14:10. The analysis has revealed a known problem with Moodle since 3.10, which continues to this day. Restoring courses duplicates question catalogs multiple times!
Removing duplicates from a running Moodle is not recommended. Instead, we have tuned the database server for the new situation until we clean up Moodle during a migration and upgrade. We apologize for the inconvenience.
