TropicalWikis has been shut down since November 2013.
TropicalWikis was losing money as a whole, and ads were not making for the shortfall. Additionally, TropicalWikis did not really take off, and other commitments made it impossible to maintain the farm.
Unfortunately we do not have backups of your wiki.
Unfortunately little progress was made. There was not enough money to go around to keep TropicalWikis running along with other monetary commitments, and I had to start axing services. TropicalWikis was on top of that list.
It is, but all good things have to come to an end.
