iPad iMessage, YouTube, app store stopped working?

[MACKA998]

Heyy,
So on Saturday my iPad was fine, even Saturday night, it was fine, working great there were no problems. Then when I woke up in Sunday morning and went on my iPad, for some reason I had to re sign into everything. All my emails, my Facebook, my app store everything and a notice even came up saying that I had to change my pass code to a different one within 60 minutes or something. So when I Went to sign into iMessage it wouldn't let me. It just says it failed to sign in and to check my Internet connection, I've tried it with 3 different wi fi connections and it keeps saying the same thing. My email is correct and my password is correct, it tries to sign in but then comes up with the fail notcie.
The same with the YouTube app, I can sign into it, but can't see any videos or anything because it simply says 'failed to connect with YouTube' however I can go on YouTube via safari and it works fine. My app store works fine as well but I cant download any apps, when I click install it just does nothing. Can some one please help me?? I have no idea how to fix this, a last resort would be to completely restore my iPad but I would rather try some other options first.
Please help!
