Admin Forum:MW message for "Sorry! This site is experiencing technical difficulties"

You know the message you get when there's a temporary problem with the site? It says something pretty close to "Sorry! This site is experiencing difficulties". I don't even have a clue what the name of the MediaWiki message might be, so I was hoping that maybe someone had altered it on their wiki and could save me the trouble of a laborious lookup. 17:38: Thu 20 Sep 2012
