After the train today http://es.wikipedia.org/wiki/Special:ContentTranslationStats works, but http://es.wikipedia.org/wiki/Special:CXStats doesn't.
It's not really a disaster as far as ContentTranslation goes except some broken links, I'm marking "Unbreak Now!" because this may mean a sitewide problem with special page aliases. AFAIK, nothing changed in ContentTranslation in this regard recently. If anybody thinks that the priority is exaggerated, feel free to make it lower.
