What's up with Nexon (i.e. Mabinogi, Maplestory, Combat Arms, etc. etc.)?

When I tried to log onto Mabi this morning, it said the website did not exist or was out of date. Then I tried to go straight to nexon.net, thinking maybe there would be a forum on something, but it said the same thing. I repeated the process for Dance Audition, Maplestory, and Combat Arms. All said that the site did not exist or was out of date. Anyone want to let me know what's wrong? :( Maybe the server's down or something....I didn't see anything about them shutting down the site.
