Hate to be the one asking that annoying question (and I don't have IRC access here) but just wondering whether I'm the only one seeing odd Wikipedia behaviour today/yesterday. The most common symptom is page timeout, but have also seen pages locked for editing (temporarily), and fr.wikipedia.org even delivered me a page in print mode when it wasn't requested.
On second thoughts I don't think it's printable mode, it looks like some lower-cost fallback mode where the skin isn't used. All the MediaWiki interface is missing, and the images are laid out in a simpler way (text then image then text...).
