Hi after much observation since sept16, there was not much change initially but the past week many problems start occuring. PIP appears longer than usual, checks arrive late, even my bank is late in clearing check. In terms of earnings per day, I did not notice significant changes. However when I log on to my adwords account, my position of my ad are higher significantly meaning some advertisers are pulling out and there is less competition. There is probably going to be credit crisis too in some countries, since most adwords users fund their account through adsense earnings and if checks are late, they can't pay their adwords account in time.
