Hi @Sajan S S ,
Thanks for posting this question in Microsoft Q&A forum and for using Azure services.
As I understand, you want to know if for UK South Region why the prompt appears that "Zone redundant for General Purpose is currently in Preview. By using this feature you confirm that you agree that your use of this feature is subject to the preview terms in the agreement under which you obtained Microsoft Azure."
The answer is that for the regions Australia East, Japan East, and UK South the feature is still in preview.
For General Purpose tier the zone-redundant configuration is Generally Available in the following regions: West Europe, North Europe, West US 2, France Central, East US 2, East US, Southeast Asia & Qatar Central.
If we select any other region, we will not see the prompt:
When the feature will be available in the above-mentioned regions, the prompt will be removed.
Hope this helps. Do let us know if further queries. Thanks
