Some Server not Resolving certain address

[Arie L. Putra]

Some of my server reported SERVFAIL,

i try some reference on http://www.whatsmydns.net/ and some result fail indeed, but why some of my server still resolve ok?
or my other server which resolve the domain actually "late" to see the invalid record?


Best Regards,

dopmain positivebrain.asia has invalid NS records. maybe a web DNS checker
