In all seriousness now that things have started catching up today is shaping up to be an amazing day so I'm wondering if clicks from yesterday (definitely below average) are being placed with todays stats.
Either way I'm not concerned, as long as it evens out overall.
Its very surprising to me that while updating yesterday's reporting Google seems to have updated my clicks and earning data well before the page impressions as if they came in two batches. Even today while my page impression reporting seem completely dead for well over 6 hours now, clicks and earning numbers are getting constantly updated.
OK, we just posted to the Inside AdSense Blog about the issue, which is now resolved. You may still see a slight delay in reporting for the next few hours, but targeting, ad serving, and stats were not affected.
