Web 2.0 error pages

After reading this post on we break stuff, the first site I visited was down for maintainence. It got me wondering who designs these pages for an organisation, is it the witty designer, the IT dept armed with fonts and stock photos or the marketing dept trying desperatly to stop valuable users drifting away? This group archives these quirky, geeky error pages that make us feel ok about stuff being broken, as I suspect they will be a thing of the past in Web 3.0!
