I contacted Nintendo and asked if they were able to turn the servers back on. But nope, they sadly can't. Many might ask, why did you contact them about this? My friends and I always played online on the 3DS after school. We are sad to jot be able to play online anymore, especially since we just graduated. I tried to convince Nintendo to turn them back on, but... they can't. Which is actually pretty sad, in my eyes at least.
