NONE of my campaigns are showing :( - What is happening to adwords?
In the vast majority of cases, when an account stops running, it will not be because of a system wide problem. At least in my (perhaps biased) opinion!
(You many not know yet that I work at AdWords.)
I stick by my usual advice in cases like this. If you see something happening in your account that you can't figure out, then use the 'Contact Us' link in your account, and ask the AdWords support team.
They'll be able to look at your actual account, and let you know what is happening.
