A situation arose on boot where the service acquired a 0-byte file from the download as there was no remote access at the specific moment it started.

This allows it to attempt to re-download next start if the file is 0bytes and IPDBNoFetch is false.

Prior to this minor fix it would EOF error on os.Open

That's strange, at some point, I'll try to prevent it from creating the file in the first place, though for now this will work :) Thanks!
