Folks - my DNS slaves are flooded with these [req from corp email gateways]:
query failed (SERVFAIL) for buildcount.com/IN/NS at query.c:4623
query failed (SERVFAIL) for rss.sina.com.cn/IN/A at query.c:4623
...
BUT if I query the very same Domain Names within googles' DNS - it's all good:
dig @8.8.8.8 buildcount.com
buildcount.com. 3600 IN A 61.136.59.34
And of course, my systems are NOT able to resolve these and other names
cause /etc/resolv.conf pointing to my local resolvers, this is just partial
list:
host treesfresh.net
host rss.sina.com.cn
host twoproperitary.ru
host qq.com
host 53www.com
host exactshy.ru
host heldthem.ru
Are these misconfigured Domains - if so - then why Google's DNS able to resolve
name, MX etc...and my DNS slaves
Thanks a lot,

Is there anything I have to enable on my side to query these "double CNAMEs"?
dig @8.8.8.8 cdn2.example.com
cdn2.example.com 3600 IN CNAME cdn2.example2.com
cdn2.example2.com 3600 IN CNAME cdn3.example2.com
cdn3.example2.com 3600 IN A 1.2.3.4
Thanks a lot guys,

Folks,
When I try to get an IP address for some sub-site/domain, let's say
cdn2.example.com --- I'm getting errors, BUT when I query
Google's DNS servers I'm getting an IP address:
dig @8.8.8.8 cdn2.example.com
cdn2.example.com 3600 IN CNAME cdn2.example2.com
cdn2.example2.com 3600 IN CNAME cdn3.example2.com
cdn3.example2.com 3600 IN A 1.2.3.4
This is my DNS configurations/errors:
