It might be because of the fact that a few weeks ago, when connecting to my stepdad's Internet, a saw something called "Primary DNS". I had no idea what it was, and it was all 0's. So I, being me, changed the setting for DNS on my DSi. I think it's, like, 18.104.22.168. And after researching, I learned that DNS is sort of like an IP address. So basically, apparently, I happened to change my DNS to someone else's, and I'd assume that they're getting all of this as well...
So, basically, if you go to your DS, DSi, or 3DS settings, go to Internet, go to advanced setup, make your connection there, turn off Auto-Obtain DNS, and put 204.045.029.054, you should get this as well XD
*EDIT* What I wrote above is the reason.
And whaddya know, I log onto to GTS again today, cuz I'm bores, and what do I get? A Kyogre. XD Yaaaay
