At this moment, the NA portal and server are not available due to serious technical issues in the data center. We are working on fixing the problems right now. In several hours most of players will be able to join the game.
Firstly, we'll bring the game's most important services back online. Players who already have a World of Warships account will be able to continue playing. To bring back in-game web services (news, clans, armory, premium store, etc.) additional time will be required.
We apologize for any inconvenience and thank you for your understanding. According to preliminary estimates, full restore will take around one day.
