Can you determine what AZ an S3 One Zone IA bucket is stored in?
If you were to store data into an S3 bucket with the One Zone IA class, is there a way to control or determine what region or AZ the data is stored in?
By extension of this, is there a way to move the data to another AZ but still retain the One Zone IA class? If there was a catastrophe with an AZ, would the survival of your data be completely left to chance because of the randomness of what AZ S3 chose when you uploaded the data?

A customer always has to choose the region to store their data. AWS does not move data between regions unless requested to do so by the customer or a valid and binding legal order.
That said, customers can not currently choose which AZ their objects are stored in for one zone-IA. Customers cannot currently choose which 3 AZs their data is stored in for S3 standard, within regions where there are >3 AZs, so no choice for One zone-IA is no different in that regard.
S3 is offered as an abstracted service which has characteristics based on individual storage classes. I'm trying to understand the use case for needing to specify an AZ for one zone-ia.
If I have an application that will consume data from an Amazon S3 bucket with the S3 One Zone-IA storage class, and I can determine the location of that data, would it be reasonable to think that the costs associated with data transfer would be virtually zero and that latency would be predictably lower? I understand that although it may not be possible to choose the specific zone where the data is stored, it would at least be useful to know in which zone it is located in order to optimize the rest of the infrastructure that will be consuming data from that bucket.
Hi Michael , I think it is useful to know in which AZ the data is hosted. I explain my reasons below.
