Nameserver is Lame?

Hello, Strange thing happened, I had a VPS which had dns1 = .185 dns2 = .186 No need to give to much information, but They responded perfectly, yes they are on the same VPS cPanel for DNS. I moved /etc/named.conf /var/named/ over to a new DEDICATED SERVER I then Arped the IP's .185 and .186 over to the server and everything was working great after a serial update, and reload. However randomly out of the blue .185 decides to become lame? Why would it become lame? I have made sure Basic setup has the nameservers, there are zones for dns1 dns2 and they are all proper, why would only 1 of them decide to become lame? When I dig

UPDATE: Right now, I am suspicious that this is my ddos mitigation 3rd party causing this issue, I don't seem to be able to see the dns1 properly from outside meaning I can ping it but If i run things like dns-record-viewer.online-domain-tools.com/ It pretty much tells us it wont respond.

Confirmed, This was the doing of our Staminus DDOS Mitigation system... Closing the ticket..
