The page you're trying to open here isn't a normal website like you're used to but actually a gopher website!
Now don't worry... all is not lost! If you're on Firefox you can download the OverbiteFF Firefox extension to add gopher support to Firefox, or if you want to go the old school way you can browse the site with a browser supporting the gopher protocol natively such as Lynx.
For Android users you can download Overbite for Android which is a native gopher browser for the mobile platform allowing you to browse all the best gopher sites with ease.
