In the previous version of the URL shortener if you visited a link that could not be found, you would be sent to the wisconsin.edu homepage.
It was found it to be a poor user experience to be redirected to a page that you weren’t expecting without notification as to why. Theming this site was avoided, as it is not meant to be a destination.
The solution chosen is to show an un-themed 404 page that notifies the user that the link was not found; they may try again, or wait to be redirected.
