I have a domain name registered with http://www.registryrocket.com/

I have found that the main site, rudolfcode.net works, but the hostgator forwarding has stopped working (firefox simply fails when you point to http://www.rudolflabs.com, which is the domain name registered by hostgator).
How can I debug this issue ?

Im not sure what the failures mean .... But Im pretty sure that "Conecting to WWW Home Page" failed is a pretty bad sign !
