Issues with iMessage and FaceTime again?

As of about 45 minutes ago, I noticed that my messages were not defaulting to iMessage. Rebooted the phone, toggled iMessage on and off and now we're stuck at the "Waiting for activation.." screen. Same for FaceTime. Dug out my iPad and it's doing the same thing.

I highly doubt geography matters, but I'm currently in Pittsburgh, PA. Anyone else experiencing the same thing?
