I have a VPS server that I host several sites on. One of the domain names I use for a site hosted on the VPS is registered through a different company.

The site was working fine until this morning when it randomly went down. After hours of talking to my hosting service support, they decided that the problem was I did not have an A record for NS1 and NS2 pointing to my name server's ip addresses and they claimed the absence of those A records are why the site went down.

I have never heard of needing an A record for NS1 and NS2 before.

I am confused as to why the site would work just fine without the A records and then suddenly go down when no DNS changes were previously made.

Could someone explain this to me?

If you don't have A records for NS1 and NS2 then how are they expected to resolve? Presumably you are specifying the same nameservers on your other domains? – w3d Jan 23 at 23:04
If you had no nameserver records it should never have worked, sounds like they are making excuses. – Toby Allen Jan 28 at 10:11

You have the static public IP for your VPS right ? that is called as A record for the DNS

If your domain service company is not providing the DNS manager , Use any cloud DNS manager , get the NS from that DNS provider , Set those NS in your domain manager and your VPS IP as 'A' record in DNS manager
