Interesting read about how Amazon Route 53 performs massively different with their 4 nameservers, despite the use of Anycast.

I find this still valid today as I observed 3ms ping latency from Vultr Tokyo for both .org and (BGP Peered with JPIX), but 50ms for .net, and an outrageous 100ms for .com.

(Same results are observed from my home network – NTT. And of course, in real world scenarios, users are most likely using recursive DNS like Google Public DNS, so authoritative DNS’ performance is neglectable.)
