Your member ID is "icloudcustomercare". Shouldn't you know the information you're seeking?.... Seriously, none of us here would know the answer to that question unless Apple makes that information available publicly, and I don't *think* they do, but I could be wrong.

Probably China. If you count the data stored on the servers there in China.
