Well the falling out between Crucibelle and Morthaur & Co pretty much stuck the knife into that place.
The odd thing is, after a few months passed, she reached out to Morthaur for some help with her computer! And unbanned him from the Island. She stated she couldn't remember what all the fuss was about.
But, I agree, that was the death blow, that and the fact that it was down for so long. By the time it came back up almost everybody moved on!
