If you're having problems resolving the domain, please flush your dns cache. There are some colleges that have their DNS servers set to ignore TTLs and therefore aren't updated as frequently as they should be.
The domain should be resolving fine for users on large ISPs.
What Joe mentioned will fix this, but you can always access the site via
