So the question is not so much "is 500ms towards the server bad", it's "can I build a single server (cluster) that will take all the load worldwide when the client software does bad things."
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. matto

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
