If possible I wouldn't try to redirect the nxdomain it breaks many things, especially domains which are down for a short while. I would like to ask you don't do that. But if really think you must and what to fix it then I would change the lua script to understand that domain.com should not be redirected. I would probably also keep the ttl as low as I possible to make problems you create go away as fast as possible, as low as I think the recursors can handle (as it will obviously get a lot more queries) with a margin ofcourse.
