whois says that it's a valid domain name, registered to Kurt Reitzel, and it points to nameservers NS1.lunariffic.com and NS2.lunariffic.com. The registrar is G-o-D-a-d-d-y (can you believe that LP censored that?). There is no server associated with the site... double check the two nameserver names you used, although if you didn't change anything... what happened? lunariffic.com seems to be up.
I guess you will have to first talk to G-o-D-a-d-d-y and see if they're having any problems. At the same time, you might open a support ticket at LP to have them look at it from their end. both "tracert" and "ping" are failing to resolve "vtonight.com". Either something's wrong at the registrar, or something is wrong with LP's nameservers.
Ya I can't seem to figure what the problem is. I opened a support ticket with LP, hopefully they can sort it out soon.
