 $$ New server deployments are temporarily blocked in these regions. Already provisioned servers are fully supported.
 
 ** Zone-redundant high availability can now be deployed when you provision new servers in these regions. Any existing servers deployed in AZ with *no preference* (which you can check on the Azure portal) before the region started to support AZ, even when you enable zone-redundant HA, the standby is provisioned in the same AZ (same-zone HA) as the primary server. To enable zone-redundant high availability, [follow the steps](how-to-manage-high-availability-portal.md#enabling-zone-redundant-ha-after-the-region-supports-az).
+(*) Certain regions are access-restricted to support specific customer scenarios, such as in-country/region disaster recovery. These regions are available only upon request by creating a new support request.
