If the site you are referring to is http://www.designcandy.net I agree that it is slowish. Reverse DNS shows it is being served from apache2-udder.toadstool.dreamhost.com.
Is it on the Blingy cluster? You can check by activating the ajaxy “Account Status” link in the upper right area of your panel screen. The server listed under “Email” is your cluster.
If it is Blingy, then you should take a look at the http://dreamhoststatus.com to understand what is happening at present … and that could also account for why you have not yet received a tech support response.
Additionally, when you are not receiving tech support responses over a several day period, it is always possible you are not getting the emails that DreamHost has sent. This is particularly likely to happen if your default email of record is a DreamHost email address on your account (since there may be a problem with email on that account!). This is one of the reasons you should always have an additional “non-DreamHost” email account set up to receive DreamHost correspondence. You can do this from within the Control Panel (“Edit Profile” - upper right corner).
Finally, to make sure you have not missed a tech support response, you should check the archives of all correspondence that DreamHost maintains in the Control Panel -> Support -> Support History screens. There you will find copies of everything DreamHost has sent you (even if the email never made it to you, or got caught in your spam filter, or whatever).
