The lights have gone out and no-one is at home at World of Warcraft's European customer support site, right now. In a message posted to a WoW support forum, a "technical issue and subsequent loss of electricity" is blamed for the outage.
If you need in-game support, then Blizzard reps from other offices around the World of Warcraft are there to help, although there may be some delays. It's assumed that the customer support firefighters are based mostly in America, as Blizzard says it would "assist our international teams if players could submit their tickets in English".
That should be easy enough for you to manage - you got this far, non?
