Has your site disappeared from the Internet? Maybe you changed hosting companies. Maybe you changed the Name Servers using GoDaddy's tools. Do not worry. Two websites are invaluable in helping diagnose DNS troubles.
<ol>
<li><a href="http://www.kloth.net/services/dig.php" title="DNS Lookup">DIG </a>on Kloth.net is a service providing the same information as nslookup. This tool helped me determine the DNS on NS1.TUXREPORTS.COM was set to an improper IP number for <a href="http://www.chemhints.com" title="Chemical Hints: A Resource for High School Chemistry">Chem Hints</a>. At the same time, NS1.PRIMARYDNS.COM had not released the DNS. Therefore, people surfing the web would not find the site.<em>* The DIG utility (domain information groper) is a unix tool, which can be used to gather information from the Domain Name System servers. It is part of the <strong>ISC bind</strong></em> nameserver software package.</li>
<li><a href="http://www.dnsreport.com">DNS Report</a> is a service providing information on the parent, NS, SOA, MX, Mail, and WWW. The site allows two free reports.</li>
</ol>
Both tools contain enough information for diagnosing why a site has "disappeared" from the Internet. Just remember to wait for DNS propagation after you have made changes.
