I am sorry to see you here, but,
Back to Normandy has been upgraded, because of security reasons, mobile use and new technology.
All the data is you were looking for is still available. And of course there are new updates!
Please use the menu's! There are two: at the top and at the right of the webpage. You can open that menu by clicking the three stripes at the upper right corner.
