Adsense Targeting Gone Bonkers?

I recently put up a new page about power meters.
AdSense immediately gave me relevant ads, and has been.
Today, it's all ringtones and medical stuff.

Has anyone else noticed a profound Adsense "loss of targeting" today?
I'm off to check other pages.

 

I had one day like this about a week ago, it really kills your earnings for the day

 

Yeah.
Just a fluke.
Must other pages looked fine.

 

I am starting to see a huge influx of ringtone ads on mine as well which are totally unrelated.

If you think it maybe hurting payouts or they don’t look well on your site then ban the url through your ctrl panel.

I think there is a huge increase in affiliate ringtone advertising which maybe causing a ripple on the publisher end.
