Very nice article. I recently switched to amazon from dyn. One thing I noticed is that amazon has unique hostnames for the nameservers. Can you comment on how Amazon's use of unique name server names impacted your results? I have a suspicion that amazon is half as fast because it requires two lookups instead of 1. ns1.dyn.org is likely to be cached, but llkadjsf.amazondns.net is unlikely to be cached.
