Notice: World of Warships is conducting another Public Test of new features. 0.5.9 version. Lots of new stuff to see and do. And you can get stuff for your 'live' account by testing these new items. Starts the 19 July (Tuesday) 2016.
Looks like it's back up now bud btw If you're looking for a group server to play in, without having to constantly worry about pvp, MOBIUS server is recommended. It's PVE only and it's about 17,000 strong.
