This seems very similar to what happened to a couple of the ORBS mirrors when ORBS shut down.

Eventually, one of them decided to just start returning "" for every lookup (or some such), which caused lots of people to reject-all-mail until they fixed their configs.

Not that I think MAPS would do such a thing, but it may be one of the few ways they can fix the large installed base pointing at them and not ceasing as they're supposed to.
