DNS traffic, surprisingly, is not very "fat". It is no HTTP nor SMTP.
The engineering behind appropriately sizing a unicast fallback would be pretty trivial, especially compared to building a somewhat-robust anycast architecture.
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. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org
