unable to access nortondns.com, but can access setup.nortondns.com

Hi folks, I have updated my dns entries for nortondns (198.154.192.1, 198.153.194.1). I get the ok page at setup.nortondns.com, however, I get a problem loading page when trying to access nortondns.com. I have tried several browsers and computers and achieved the same results. Thanks
