General Purpose service tier zone-redundancy availability
Minimize impact to your data in the event of an outage to an entire zone by enabling zone redundancy. Zone-redundant availability ensures your data is spread across three Azure availability zones in the primary region. For more information, see availability through redundancy in Azure SQL Database.
For up to date information about the regions that support zone-redundant databases, see Services support by region.
For General Purpose tier, the zone-redundant configuration is available in the following region:
- China North 3
