I registered for dreamhost and a domain 2 and a half days ago at least and my website still isn't up. Could there be something that is holding it back? The address is http://www.curlybro.com.
DNS Propogation is out of the reach of Dreamhost. However, your domain doesn't seem to be listed as being registered yet, which is registeration, not propogation.
Have you tried emailing support? They are pretty good at getting back to you.
