Video file produced by us has been marked as copyright violation by the company I use to host large files (no we were not filming copyrighted subjects / objects). Repeated requests to restore access to file so our customers could download it ended up with customer support repeating the same thing ad nauseum. I have better things to do than waste my energy on this and since it was just a single file I just hosted it in a different place.
