Everything Google seems "buggy" to me lately. Slowness logging into gmail and gmail login page even loading. My guess is that they are making a LOT more back-end changes than normal. That said, AdSense has been challenging month. Lots of odd advertisers showing up for me when I changed nothing and a lot more duplicate ads on the same page than I've ever seen before. I just don't get the wild CPC swings I have seen across multiple AdSense accounts this month.
