Tomorrow, on 26th March 2013 at 10:00 CET (09:00 GMT) the support server will be restarted. This maintenance should last approximately one hour and during this period of time you won’t be able to submit a ticket to World of Tanks Customer Support.
Once the maintenance is completed, you will be able to do so as usual. Please note that other services such as the game server, forums and official website will be running as usual.
Thank you for your understanding.
