I thought that it had already been revealed that they have collection centers all over the world. I remember reading that in one of the articles I've read on the subject, but now I can't find it. So maybe I'm misremembering.
Anyways, it wouldn't be much of a surprise to me to hear that they have collection centers in other countries. I already pretty much assume that they do.
Edit: I found some evidence. Look at the leaked slides on Boundless Informant [1]. It mentions having sites in "regions" and querying for what kind of coverage we have for a given country. It doesn't explicitly say that "region" means a world region. It could just as easily mean a region inside the US, but I think that would be awkward terminology when the rest of the document has a global scope.
