This tutorial is operating under the assumption that you are using SSH. Details for how to perform similar steps in a browser will be added later.


Step 1. Check the official nameservers for the domain with:

          whois domain.com

Step 2. Check that the DNS records are @ the official nameservers:

          dig +short @[nameserver] domain.com type
          ex.  dig +short @ns1.west-datacenter.net ifurniss.whsites.net 

Step 3. Verify when there may have been a recent change to this domain.

Step 4. Check on DNS propagation to see if this appears to be the issue:

          http://whatsmydns.net/#A/domain.com
          ex. http://whatsmydns.net/#A/ifurniss.whsites.net/
