Dreamhost got back to me about the links that are now working:
It seems the dns for those domains was incorrect. I updated it in our
database and flushed our nameservers, so they should start working for
you as soon as your isp's nameservers clear their caches.
The one that is working at the moment is http://irishbornchinese.com.
http://irishbornchinese.kaykays.com is still down. Will check later in the day.
