Azure Database For MySQL Flexible Server February 2024 Maintenance

We're pleased to announce the February 2024 maintenance for Azure Database for MySQL Flexible Server. This maintenance mainly focuses on known issue fix, underlying OS upgrading and vulnerability patching.

Note

During the preliminary stages of our February-March maintenance period, we identified a regression issue that necessitated a reevaluation of our scheduled maintenance activities.

We are currently in the process of rescheduling these maintenance activities. Affected customers will be promptly notified of the new maintenance timetable. We apologize for any inconvenience this may cause and thank you for your understanding and continued support.
