503.html (the "Service Temporarily Unavailable" error page; can be viewed while the servers are up by replacing "wiki/(whatever)" with "503.html" in the URL) is not translated from English to other languages, even if the MW interface is set to another language. (I tested this with de.wikiquote and fr.wikisource.) It should be translated because some people don't understand English, or are bilingual but think that a website in their primary language displaying an English error page is a sign that the developers are too lazy to i18n.
