And I think LanGuy99 did some ping tests, and SecureDNS did great.
Ping test is only relevant when comparing *.*.*. *.*.*. 22 and 25, but they are in the same subnet. I can not understand why Comodo has made the division into non-english countries. For me traceroute identical.
When comparing multiple DNS services important criterion is not ping, important time for the server processes the request and gives an answer. Ping test is just a test network - should do when choosing the DNS provider has already been made and he has several sets of IP addresses.
