Today all numbers in my AdWords campaigns dropped to absolute zero. Usually 300-400 clicks/day. I haven't even looked at the UI or made any AdWords changes in at least a week. No billing alert or any other alert in the UI that I can see. Credit card is wide open. Website is up and receiving normal organic Google traffic. Any ideas?
