Has anyone noticed CPC's being taken off of any of their sites?

Today when I logged on to some of my best sites a lot of them had their CPC's or the daily clicks taken off. It sucks because some of them had over 50 ads a day each of them ranging anywhere from 3 to 5 cents. So that's at least a guaranteed dollar. One of my sites had 20 cent clicks at one time and then lowered them to 10 cents. Now all of their clicks are gone. That site could earn you at least a guaranteed 3 dollars each day pretty much. If you do that each day for a month that's an extra ninety dollars. I hope that these sites can get their CPC's back soon because they were awesome earning opportunities. Some of my sites still have theirs though which is strange.
