I need a little bit of guidance. I had set up a hosted zone in AWS with my domain name. I deleted that when I opened my InterServer account. Unfortunately, now my domain doesn't resolve. Can someone point me in the right direction to correct this?
With out knowing the domain I would say your current nameservers do not resolve any records. Once the dns servers are changed at the registrar it wouldn't matter if your domain had records on another dns server because they are not going to be used.
You are able to use cdns1/cdns2.interserver.net by using my.interserver.net and going to the domains -> dns manager section to get the domain back online even if you do not currently have any active packages in your account.
