In this question, there is a proposed solution to preview the Word files with Google and Microsoft viewers. Both solution work pretty well, but there is a restriction for this project that the documents can't leave Europe.
I am wondering the following questions:
- Does Google/Microsoft store the files on their server after they have downloaded it? I see that the file download does not happen in the browser, but in both cases it is served as image.
- If the request is from Europe, is the document processed on European servers? And if no, is it possible to somehow influence it?
Here are the examples for the convenience:
PS: in case it is relevant, the document itself is stored in Google Storage European region.
