Is your cell phone service down?

[luv]

I like a certain restaurant on Facebook, and they posted earlier that, if you're one of 10 million people without cell phone service, and you go in and tell them the name of your carrier, you'll get 10% off your order.

Then, I overhear an attorney on the phone saying that he and his wife's cell phones both stopped working simultaneously. They're on AT&T.

Anyone else having this problem, or is it just a local thing? Like maybe a cell tower down?
