Alright, I bit the bullet for everyone and checked goatse.cx; doing so gets you the following message:
ALERT
The CX Registry has shut off the goatse.cx domain suddenly and without warning.
They have cowardly cited a section of their AUP with allows them to remove sites at their discretion.
Please e-mail
info@nic.cx with your opinion of this matter.
It also contains a link to "the original page", which I assume contains the infamous goatse picture.
