The servers will be shutting down (Tri) on April the 30th.

Direct quote:As we usher in the exciting new Monster Hunter 3 Ultimate games, we unfortunately will be transitioning off the Monster Hunter Tri servers for Wii. This won’t happen until April 30, 2013 however, which will be 6 weeks after the launch of Monster Hunter 3 Ultimate. With the new title, there will be a new place for all of you to gather and hunt online with each other, and we hope you will continue to play together on Monster Hunter 3 Ultimate.
