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.
It won't generally affect the real user test results because of a warmup/training phase in the test when those DNS records would be cached within the recursive chain.
