On my dedicated server at server4you.de I had theese nameservers preconfigured:
nameserver 22.214.171.124 nameserver 126.96.36.199
they were unable to resolve my domain names 2xfun.de and 2x.to
i ran some dns check like here http://www.intodns.com/2xfun.de and everything looked fine.
after changing the nameserers to googles 188.8.131.52 and 184.108.40.206 everything resolved perfectly.
Is there anything wrong with my zones?
