Just a general service announcement: Nintendo is ending its Nintendo Wi-Fi Connection service for both DS and Wii in the next day. It's unclear when it will officially go offline, but it's happening soon.
This change impacts online multiplayer, matchmaking, and leaderboards. This does not mean Nintendo is shutting down the eShop on the Wii or DS. Those will continue to function (for now?).
Obviously, this won't impact offline games.
The full list is available below, and further details are available on Nintendo's website.
