For a few days now, none of the biggest search engines have been able to find any good results for some of the wikia pages. Whereas previously a search term would have returned a wikia page as a first result, now the obvious result has completely disappeared from search engines.
This seems to affect many other wikias too, but not all. Also, I've tried searching with Google, Yahoo! and Bing. All of them behave like this.
Does anyone know the reason for this and if a fix is to be expected anytime soon?
