The Game is now back up and accessible. Due to a Hard Disk failure shortly before Christmas in our main server (jpaweb01) we have had to move the pages to another server. The login link "http://jpaweb01.planetarion.com/login.pl" should update to point to the correct place, but due to the nature of DNS servers this could take up to a week.
In the meantime you can access the game via http://patest.planetarion.com/login.pl if the other link isn't working.
Apologies for the downtime caused by this hardware fault.
