I agree with Capt Del. Just relax a little and things will come back to normal. When they do maintenance and or upgrades these things can and do happen, in fact it is pretty normal to have some bugs and glitches during this process.
Anytime you bring down a database or server no matter how much you plan ahead of time when doing it "live" the results usually differ than when testing it or planning it all out .
Take a deep breath, now let it all out .... better.
