Sounds like a DNS issue. I would first clear your home PC's DNS cache to make that that there are no conflicting DNS records between your old ISP and your new ISP.

From a command prompt, type the following:
C:\ipconfig/flushdns

Try to access the site. If it fails to work, then try it this way from an Internet browser:

http://70.85.164.5

Good luck,
