Traffic implications of DNS Prefetching
http://j.mp/eyNTx1 (pinkbike)
"Recently I received a call from our $2/month DNS service provider
explaining that our DNS queries have increased to 400 million
authoritative queries per month (a high of 120 queries/second) ,
putting us outside the scope of the basic service and we were required
to upgrade to a premium service in the range of $1600/month. After
some investigation we determined that browser DNS prefetching was
causing an increase in our authoritative DNS queries of a whopping
800%. A single meta tag to control prefetching reduced our DNS
queries by 350 million per month. The same implementation on a larger
site, deviantART, reduced authoritative DNS queries by 10 billion per
month."
