Warhammer Online main website isn't working (click the link for yourself to find out), or why you may be having connectivity issues with the game, it's because their ISP just did something they didn't want to happen.
Mythic Entertainment (not like you can reach that website either, right now) is aware of, and on top of, the issue. Currently players are unable to connect to the patcher servers, meaning that new players will not be able to get back into the game until these issues are fixed.
In the mean time, until everything comes back online, all pertinent data on the status of Warhammer can be found through Andy Belford's Twitter account, @Andy_Mythic. He'll keep players apprised of the situation until the main website can be brought back online.
