Azure storage: New required VNet subnet IDs

Note

This behavior change applies only if you use Azure storage firewall in the following regions:

  • East US 2 (azeastus2)

  • West US 2 (azwestus2)

In a future release, Snowflake plans to expand its support for the East US 2 (azeastus2) and West US 2 (azwestus2) regions. To ensure Snowflake can access your Azure storage linked to an existing external stage or external volume, you must add new VNet subnet IDs to your allowlist.

To retrieve the full list of subnet IDs, use the SYSTEM$GET_SNOWFLAKE_PLATFORM_INFO function and add a network rule for each ID. For full instructions, see Allowing the VNet subnet IDs.

Before the change:

The SYSTEM$GET_SNOWFLAKE_PLATFORM_INFO function returns the IDs of the original VNet subnets in which your Snowflake account is located.

After the change:

The SYSTEM$GET_SNOWFLAKE_PLATFORM_INFO function returns the IDs of the new VNet subnets in which your Snowflake account is located.

To ensure that Snowflake maintains access to your storage, you must complete the steps in Allowing the VNet subnet IDs.
