Perfom a different type of test on the same domain:
NSLookup Gateway - Queries 10 major US nameservers and several foreign nameservers. Custom NSLookup Gateway - Do your own lookup off of the DNS server that you want. MXLookup Gateway - Same as above, but it looks up the MX (Mail Exchanger) for hosts. Whois Lookup - Checks domain to see if its registered. And if so, it provides info on it. Traceroute Tool - Traces the route to said host and sends 10 packets and reports the results. Long(er) Traceroute Tool - Traces the route to said host and sends 50 packets and reports the results.
