Zone Redundant HA cannot be enabled on Azure flexible Postgres Server in region usgovvirginia

Question

Zone Redundant HA cannot be enabled on Azure flexible Postgres Server in region usgovvirginia

Granot, Ofir (RIS-TLV) 20

I fail to create a production Azure flexible Postgres Server with Zone Redundant HA in region usgovvirginia, does this region support only SameZone HA redundancy?

az cloud show --query name -o tsv

AzureUSGovernment

az rest \

> --method get \

> --url "https://management.usgovcloudapi.net/subscriptions/${SUB}/providers/Microsoft.DBforPostgreSQL/locat… \

> --query "value[].{zone:zone,supportedHAMode:supportedHAMode,zoneRedundantHaSupported:zoneRedundantHaSupported,geoBackupSupported:geoBackupSupported}" \

> -o json

[

  {

	"geoBackupSupported": true,

	"supportedHAMode": [

	  "SameZone"

	],

	"zone": "none",

	"zoneRedundantHaSupported": false

  },

  {

	"geoBackupSupported": true,

	"supportedHAMode": [

	  "SameZone"

	],

	"zone": "1",

	"zoneRedundantHaSupported": false

  },

  {

	"geoBackupSupported": true,

	"supportedHAMode": [

	  "SameZone"

	],

	"zone": "2",

	"zoneRedundantHaSupported": false

  },

  {

	"geoBackupSupported": true,

	"supportedHAMode": [

	  "SameZone"

	],

	"zone": "3",

	"zoneRedundantHaSupported": false

  }

]

The error which I get is
│ Status: "HADisabledForRegion"

│ Code: ""

│ Message: "HA is disabled for region usgovvirginia."

│ Activity Id: ""

The pg flex sku is GP_Standard_D4ds_v4 and according to MS Azure document it should be supported:
https://learn.microsoft.com/en-us/azure/postgresql/overview#azure-regions

At this MS Azure official document it says that region usgovvirginia supports Zone-Redundant HA with compute v3/v4

Region			Intel Compute	AMD Compute	Confidential Compute	Zone-Redundant HA	Same-Zone HA	Geo-Redundant backup

US Gov Virginia	✅ (v3/v4)		❌			❌						✅					✅				✅

Welcome to Microsoft Q&A

Hello @Granot, Ofir (RIS-TLV) I hope you are doing well.

The az rest output shows that zoneRedundantHaSupported is false and supportedHAMode only returns SameZone for usgovvirginia. This indicates that the service currently does not expose Zone-Redundant HA in that region, which explains the HADisabledForRegion error.

It appears there is a discrepancy between the current service capability and the documentation for that region.

Please check the following:

Verify the regional capabilities using the Microsoft.DBforPostgreSQL/locations REST API, as you've already done.
For now, deploy using Same-Zone HA if your workload must remain in US Gov Virginia.
If Zone-Redundant HA is a hard requirement, consider using another supported region where this capability is currently enabled.
If you believe this is a documentation inconsistency or an unexpected service behavior, I recommend opening a Microsoft support request so the product team can verify whether this is a documentation issue or a feature rollout delay.

Thank you Jose :)
I had tried to open a support request but the region US Gov Virginia was not even at the regions drop down list, so I could not open a support request for it

As a workaround, you can try the following:

Create the support request under Azure Database for PostgreSQL without selecting the specific region (if the portal allows it), and include US Gov Virginia in the problem description.

If your organization has a Technical Account Manager (TAM) or Unified Support contract, they may also be able to route the request directly to the PostgreSQL product group.

Since the REST API reports zoneRedundantHaSupported: false while the documentation indicates that Zone-Redundant HA is supported for US Gov Virginia, I believe this should be reviewed by the product team as it appears to be either a documentation inconsistency or a service rollout issue.

Thank you for bringing this to our attention.

Answer 1

Region US Gov Virginia currently supports only Same-Zone high availability for Azure Database for PostgreSQL flexible server. Zone-redundant HA is not available there yet.

From the high availability limitations and considerations:

High availability with both replicas in the same zone (Same-Zone HA) is available in all supported regions.
High availability with zone redundancy is available only in certain regions, as listed in the Azure regions section.
If a region consists of a single availability zone or does not yet support zone-redundant HA, only Same-Zone HA can be enabled.

The zoneRedundantHaSupported: false values returned by the az rest call for all zones in usgovvirginia match this behavior. The HADisabledForRegion error indicates that zone-redundant HA is not currently enabled for that region, even though the documentation table shows that the region is planned/marked as supporting zone-redundant HA with v3/v4 compute.

In this situation:

Use Same-Zone HA in US Gov Virginia if HA in that region is mandatory.
If zone-redundant HA is a hard requirement, consider deploying in another region within the same geography where zone-redundant HA is available, as suggested in the regions documentation (for example, choosing an alternate region in the same geography that lists zone-redundant HA as available and is actually enabled in practice).
Monitor the Azure Database for PostgreSQL regions documentation for updates; when zone-redundant HA is fully enabled for US Gov Virginia, zoneRedundantHaSupported will report true and the HADisabledForRegion error will no longer occur.

There is no configuration change on the server side that can override this; it is a regional capability flag controlled by the service.
