By default, Azure SQL Managed Instance achieves availability through local redundancy, making your instance available during maintenance operations, issues with data center outages, and other problems with the SQL database engine. However, to minimize a potential outage to an entire zone impacting your data, you can achieve high availability by enabling zone redundancy. Without zone redundancy, failovers happen locally within the same data center, which might result in your instance being unavailable until the outage is resolved - the only way to recover is through a disaster recovery solution, such as through a failover group, or a geo-restore of a geo-redundant backup.
