Inside AdSense: Pageview tracking back to normal

Inside AdSense: Pageview tracking back to normal: If you're displaying multiple ad units on your pages, you may have noticed that your pageviews were higher than normal for part of yesterday and today. Our engineers identified a bug which prevented ad units from detecting other units on the same page. As a result, our system logged a pageview for each ad unit that was loaded on a page, instead of a pageview for each page containing ads. In some cases, this also may have caused specific ads to appear in multiple ad units on the same page.More from source
