Later today I am aiming to apply a site-wide update, the application of this update may take a few hours during which time the site will be unavailable or only partially operational. I expect to start this work at approximately 6 PM GMT (1 PM EST). As soon as the update is complete I will add an update to this news article. This update is both infrastructure and cosmetic based, it delivers equal 160 pixel columns (for information and advertising) left and right of a wider center column, it will also enable us to deliver new site features more easily in the future. Any cosmetic issues after the update should be resolved by a 'hard refresh' (hold CTRL or APPLE while clicking reload) or clearing your browser cache.
