This statement may be true for many DNS servers, but I suspect it
is completely false for the roots, or for the GTLD's. Perhaps the
folks from .org or from f-root would like to comment on how hard
it would be to handle the whole load from a single box, particularly
when you consider they are all high profile DDoS targets as well.
If it were trivial, more GTLD's would be doing it.
