Hope some one will help me in resolving the issue. My Domain name is "prohosterz.com"
Google Public DNS is returning a SERVFAIL for my domain:

I don't have any issues resolving my domain against OpenDNS:

$ dig prohosterz.com @resolver1.opendns.com

; > DiG 9.9.2-P1 > prohosterz.com @resolver1.opendns.com
;; global options: +cmd
;; Got answer:
;; ->>HEADER
I don't know why google servers do not resolve my name, if anyone have any explanation please let me know.

A:

It looks like your DNSSEC configuration is broken.
The delegating nameservers (for com.) are serving a DS record for your domain, but your own nameservers do not supply DNSKEY nor RRSIG records.
Did you forget to sign the zone?
The reason it works with some recursors is that those recursors are not DNSSEC-enabled and thus don't catch the problem.
