I've been having problems with getting an "Unknown Host" page every time I buy a new domain.
wendywilliams.info is a new domain of mine and it's having the same problem. I purchased it over a week ago so it's not due to other servers not getting updated.
Your default name servers are set to "Dynadot Web Hosting". But that setting only works if you also have a webhosting package with us for that domain. That is what is causing the unresolved host problem.
You should set your default name servers to parking, or forwarding to another domain.
