What could be the problem? Can't access websites ending .zz.mu

Hello!

I'm having issues accessing websites ending with .zz.mu (because I have a website of my own with that extension). I'm getting a blank page. My friend says she also gets a blank page when accessing those sites such as http://www.aduls.zz.mu/

What do you guys think is the problem? Do you think this will get resolved on it's own? Should I go to another hosting service for my website or just wait?
