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.
