Hi Jiankang,

What reason do you have to think that response latency from root servers 
has any measurable impact on end-user experience?

Queries to root servers from individual clients are sent very 
infrequently, in my experience; the TTLs are not short. The probability 
that any client of a real-world resolver gets a delayed response because 
of latency between the resolver and a root server seems vanishingly 
small.
