Automatically when your account is created, we have set up our servers to make a simple website to occupy your domain name until you have uploaded your website.
We do this so your domain name does not show your visitors the 'Page not found' screen and looks a little nicer for visitors to your domain name until you have put a site in place.
You can delete this from your public_html folder at any time and will not affect your service should you not want it to show up there.
NOTE: This will only be shown on new packages from DanumHost and not on any subdomains or newly created add-on domains.
