Impressions / clicks almost 50% lower?

Has anyone else noticed about a 50% drop in clicks / impressions on the stats from the 11'th and 12'th?

I just finished checking my server stats, and my sites have actually been getting more traffic within the last two days. My Adsense stats are pretty much the same, but my YPN impressions/clicks have been almost cut in half.

 

maybe your fill rate is lower

 

there was a bug in their system where ypn ads werent being shown to people from certain isp's. i believe it was a dns issue. according to yahoosarah, this has been resolved as of yesterday.

 

I noticed a 30% drop in impressions yesterday although my server stats showed no such drop. And RPC is half of what it was 3 days ago.

 

My impressions aren't lower, but my payment has never been really high with YPN.

 

Yeah I had the same issue with the clicks on these days, I thought that was only me. The impressions were ok though.

 

May be it because of higher Internation traffic. Yahoo don't pay for international. it only pays for USA.
