I don't have hard technical info. But here is what I have:

Raw facts (.CA used as an example):

What follows is a personal troll, you may skip it if you want the
discussion to remain calm and professional:

Giving the FUD-based marketing of UltraDNS, it is funny to see a
competitor giving them a taste of their own medecine. (See Mark
Jeftovic's excellent comment in the CircleID discussion.)
