On one hand, Aurora and the forum/wiki are hobbies run by Steve and Erik respectively (I think that there's a donation link somewhere to help cover costs), so we shouldn't expect the uptime that we see from billion/trillion-dollar internet corporations.
On the other hand, I too was dismayed at the prospect of one of the Internet's great works of art disappearing into the Aether. There's a lot of passion and authenticity here that you don't see in modern social media.
