Looking at server logs everything appears to be normal, but I won't really be able to tell until awstats updates. Unfortunately analytics isn't even showing for today yet on this site.
Does google screw up it's reporting sometimes?
<added> I saw this same thing with another site of mine a few days ago, yet looking at server logs there was not an increase in traffic even though adsense reports a huge increase in impressions </added>
