You're welcome to give it a whirl to come up with code to do the testing
but doing it on start-up is likely bound to have lots of problems with
servers rebooting that don't have net access yet, etc.

As I put on the bug, I think the best solution will be something that
internally monitors for block rules and if triggered, stops queries to
those BLs for an hour. Then it can try again. Your idea might be
better and I'm having forest for the trees vision.
