If anyone wonder why the server is offline its because of that if you didnt see
we’re conducting server maintenance starting from 00:30 (CET) on December, 5th 2018. Our web site and the game servers will be unavailable during this time.
This move will most likely take several hours. Servers will be booted back up as soon as possible, unfortunately we can not give you an exact ETA for this, so please keep an eye on your forums.
The reason for this is the relocation of our datacentre: it is possible that the maintenance will last longer than usual. In future we will have access to better technology to provide an even smoother game experience.
