Answer 1

This is an action of the Content delivery network used by Facebook. They decide where to serve you the content from. You have no control over where it comes from.

If you REALLY want to maintain a constant URL to a certain resource, you might want to try serving that file locally. Download it to your server and manually specify the URL.
