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
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
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?
