Can't pull up 1 website: www.marymount.edu.

Every other web site that I pull up opens fine, but when I type www.marymount.edu into the address bar, the ubuntu system acts as if it is working, but it never goes to the page. It takes so long to get to the page until finally it will go to the error page. Usually when I go to different sites, I see a little bar in the lower right hand corner which turns from white to orange to indicate the progress of the page opening. When I type in www.marymount.edu, the bar stays completely white. No progress at all.
