Adsense problems today?

Has anyone noticed their google adsense earnings being lower today? I am getting the same amount of traffic as normal but I think adsense isnt being displayed to every visitor for some reason.

Adsense Earnings are different from day to day, you'll get $1.00 for a click in Friday and you'll get $0.01 for the same ad and country in Monday... this is not a secret... just go over, wait for tomorrow i have the same issue, but not only today, for long time already i know when and how much i can get for a click from USA/Canada for my main niches.
i did some tricks with traffic before, and in Monday, i've spended $100 and earn under $10, and in Friday, for example, spend $100 and earn over $400-$500, and in Saturday, i've got Banned for my Test's ))
