This is my dns lookup status getting from cpanel network tool.

Code:
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6_4.5 <<>> allpreview.net
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 9878
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;allpreview.net.			IN	A

;; Query time: 0 msec

;; WHEN: Sun Sep  1 12:43:19 2013

At now my site can not open. I dont understand what mean with SERVFAIL status but I guess its causing my site problem. I was contacted my domain support and they're said if my domain have no issues with new DNS. Its really confusing for me.
