Heh.  I'll send you some coffee.

Yes, I hope that UltraDNS implements something like this, if they have not
already.  It's still not a guarantee that things will get withdrawn -- or be
reachable, even if working but not withdrawn -- in case of a problem.  That
still leaves the DNS for a gTLD at risk for a single point of failure.

Maybe I should just chalk this up to history at this point.  I have a
feeling, though, that the head of this thread's archive URL will show up as
a citation some time from now when something else goes wrong with the zone.

<sigh>
