For yesterday (10/5) GA shows a traffic drop off on the order of 20% for my largest site (the drop off shows up in unique visitors and page views). I see a similar drop with some of my other sites, but they have less traffic and it's hard to know for sure if the effect is there.
When I look at my page impressions for Adsense, everything for yesterday looks quite normal. The size of my zipped log file (bytes) for yesterday looks normal. My server's analytics report for yesterday hasn't been generated yet (I guess, or else I don't get the stats until tomorrow with it), so I can't check there. My site's bandwidth usage for yesterday looks fairly normal.
Is anyone else seeing some abnormality in their GA reports for yesterday?
