My friend said his was slow, however mine was fairly average.

Disgustingly average here.

Did I have a totally out of the normal day or was AdSense serving affected?

The premise of the thread would've been indicated by a sudden drop in either traffic and/or AdSense ad impressions. A serious dip in ad impressions while your site stats claimed your traffic was the same would've indicated that AdSense wasn't serving up as many ads and potentially affected.

Therefore, since you didn't indicate any traffic or ad impressions, it's highly unlikely the DOS was only impacting your visitors ability to click the ads being served.

Besides, I had a stellar day ;)

My logs indicate a slightly higher than average traffic and page impressions day whereas AdSense Page Impressions were a good 15% down plus my EPC was also -23% compared to the past few days let alone month.

Interestingly today's metrics, so far, have all gone back to normal therefore I can only write it down to a TGG...a Thursday Google Glitch specifically designed to pi$$ me off:-)

very low earnings here too these few days

For me, August is not nearly as good as July was! No idea WHY though.

Agreed, August is quite a bit down thus far.

No way dudes. AUGUST ROCKS!

Low earning day today

Extremely low earnings today. It's 03.42 and my earnings are at 17.00 levels.
This is after I used the new blocking filter.

My earnings are not LOW or horrible, just not as good as July because incrediBill, JULY REALLY ROCKED! lol
