Does Dreamworld for Pokemon BW or B2W2 still work?

I am wondering does the dreamworld for pokemon black/white or black 2/ white 2 still work?

Solution 1:

According to this article dated July 1, 2013:

The Pokémon company decided that keeping up the Dream World servers is too much of a cost, or they just really want you to buy X&Y. Either way, starting from October 12th, the X&Y release date, new user accounts can’t be created anymore. On January 14th, the following services stop working:

• You can’t play the mini-games to get the hidden ability Pokémon anymore. Putting new Pokémon to sleep will be blocked earlier, starting December 10th. You can still , wake your Pokémon up in your games, even when the service is down.
