 # Reliability in Azure Bastion
 
 This article describes reliability support in Azure Bastion and covers both intra-regional resiliency with [availability zones](#availability-zone-support) and information on [cross-region recovery and business continuity](#cross-region-disaster-recovery-and-business-continuity).

-
 For a more detailed overview of reliability in Azure, see [Azure reliability](/azure/architecture/framework/resiliency/overview).
 
 ## Availability zone support
 
 [!INCLUDE [Availability zone description](includes/reliability-availability-zone-description-include.md)]
 
-Currently, by default, new Bastion deployments don't support zone redundancies. Previously deployed bastions might or might not be zone-redundant. The exceptions are Bastion deployments in Korea Central and Southeast Asia, which do support zone redundancies.
+
+Bastion support for availability zones with [zonal](./availability-zones-overview.md#zonal-and-zone-redundant-services) configuration is currently in preview. A zone-redundant configuration is not supported.
+
+Previously deployed Bastions may or may not be zone-redundant and these are limited to the following regions:
+- Korea Central 
+- Southeast Asia
 
 ### Prerequisites
 
+For a zonal deployment, your Bastion resource must be in one of the following regions:
+
+- East US
+- Australia East
+- East US 2
+- Central US
+- Qatar Central
+- South Africa North
+- West Europe
+- West US 2
+- North Europe
+- Sweden Central
+- UK South
+- Canada Central
+
+### SLA improvements
+
+There is no change to pricing for availability zone support.
+
+### Create a resource with availability zones enabled
+
+To choose a region for a zonal configuration:
+
+1. Go to the [Azure portal](https://portal.azure.com).
+1. [Create your Bastion resource](/azure/bastion/tutorial-create-host-portal).
+
+    - For **Region**, select one of the regions listed in the [Prerequisites section](#prerequisites).
+    - For **Availablity zone**, select the zones.

+
+>[!NOTE]
+>You can't change the zonal availability zone setting after Bastion is deployed. 
+
+
+### Zone down experience
+
+When a zone goes down, the VM and Bastion should still be accessible. See [Reliability in Virtual Machines: Zone down experience](./reliability-virtual-machines.md#zone-down-experience) for more information on the VM zone down experience.
+
+### Migrate to availability zone support
 
+Migration from non-availability zone support to availability zone support is not possible. Instead, you'll need to [create a Bastion resource](/azure/bastion/tutorial-create-host-portal) in the new region and delete the old one.
