Well, that's something for the root server operators to think about and
discuss amongst themselves. I know several of them are reading this list,
and may be reading this thread. 8-)
Still doesn't help .ORG, which is 100% anycast and thus has no DNS-based
redundancy (see my experience elsewhere in this thread).
