Test page even after deleting User

Hello,

I was having problem with a domain as it was just showing the centos Test page. I deleted that user and domain and created a new user and uploaded files but nothing got changed. Now I have deleted the user and domain but still that domain is pointing to the centos Test Page. I have checked the following:

Zone files: and I didn't find any entry of that domain
vhosts files: and I didn't find any entry of that domain
named.conf: and I didn't find any entry of that doemain

When i use the command:

[root@server var]# host domainname.uk
Host domainame.uk not found: 2(SERVFAIL)

[root@server var]# dig domainname.uk

; <<>> DiG 9.9.4-RedHat-9.9.4-73.el7_6 <<>> domainname.uk
;; global options: +cmd
;; Got answer:

I am not sure about the DIG's output.


Please suggest me what I can do to correct this problem.


Thanks,
Nauman
