The Guardian has redesigned a page that it hopes you will never see.
Martin Belam explains
In an ideal world, you'd never see one of the things that our front-end developers have recently been working on. It is a new version of the page that appears when there is an error on the site - most usually a 404 error.
He adds that
Our old 404 page had a list of links to various areas on The Guardian and Observer sites, but the new version more closely mimics the standard navigation that should be familiar from nearly every other page on the site.
