Was logged in, wouldn't let me join again, now won't let me log in at all

This is pretty annoying. I was logged in and then it wouldn’t let me play any games, including solo battles. I logged out, and now it won’t even let me log back in. The first time I tried to log back in it gave me an error saying that the servers are full?
I know you guys just released a new update/package with the adventure pouch or whatever, but why not get a bigger server for these events? There’s no point in having some goody if some of your users can’t even log on to use/get it.
