You can now take advantage of near-zero-downtime maintenance for Azure Database for MySQL – Flexible Server with high availability (HA) enabled. This capability is now generally available and is supported by our new HA architecture based on a dedicated Azure Standard Load Balancer design. With this release, planned maintenance operations are applied seamlessly without disrupting your application’s connectivity or performance.
Thanks to the dedicated Standard Load Balancer design, maintenance is now faster and no longer impacted by client-side DNS caching, which previously caused brief connection drops in some scenarios. This enhancement ensures that your mission-critical workloads remain continuously available, even during infrastructure updates, helping you meet strict uptime requirements and maintain operational continuity.
