Problem in opening a link

Hello! I tried to open www.gubbagroup.com, and after a few seconds this Error displayed.
How do I know that the site is still there?
I tried opening it in another browser but it also took so much time that it would show a runtime error especially in IE.

404 Not Found – Mozilla Firefox
