@ Makin, Menntarra, & Sgt_Kickaxe: do you have a high % of ads above the fold vs % of content?

No I don't. If you're worried about an above the fold penalty switch your big square ad in the top of your content to a 234x60.

More info: This only seems to be affecting my U.S. traffic

I changed some things and then it came back over the weekend. Now it's gone again.

I noticed that too, a lot of my keywords/pages saw a huge traffic spike on the 19th and into the 20th and more importantly it converted at a record rate. That was nice while it lasted.
