Okay, I signed up using the option for my own domain (since I already had one). I plugged the nameservers into my DNS settings on my registrar (1and1 in case the info helps anybody) and waited. Now, more than 24 hours later, I'm still seeing the 1and1 splash page for my domain. I also can't login to my domain's cpanel, nor can I login to HelioHost's cPanel thing on the front page.
Is this HelioHost or 1and1's fault?
