I get a "CAS is unavailable" when I go to the Portal, What do I do?

Updated

Sometimes when you head to the UArts Portal, you will encounter a strange error. The page will load and you will see "CAS is unavailable". Refreshing the page or browser doesn't seem to fix it. This is caused by your browser saving a bad version of the site to help speed up load times. Often this bad version comes from an outdated link or an old bookmarked URL.
