Re: [DNSOP] I-D Action: draft-ietf-dnsop-dns-tcp-requirements-05.txt

Thanks Duane,

For what is worth, I took a look on volume of TCP queries over the years 
reaching each Root Servers letter, just to have a feeling on how TCP 
traffic is evolving on DNS:

https://github.com/gmmoura/root-RSSAC002-timeseries

It seems that DNS over TCP is slowly increasing for most letters, and 
still under 10% for most letters.

/giovane

ps: thanks for your  https://github.com/rssac-caucus/RSSAC002-data data 
repository, helps tons.
