@Martin I've been finding the exact same thing (UK). It's really unusual as evenings used to be busier. I've stopped myself from looking in the evening as it was making me feel ill (lol?), so couldn't comment if the results are any different.
During work hours though, I am quite happy with the results and conversions are now better than ever. That was until today... they just hit the floor again! Number of visits appear to be normal.
SERPs look relatively stable, although they do flux a bit - I know on a few of our affected brand searches we are up 5/6 places on last week. The rest of the site is, as ever, relatively unchanged.
I wonder what tomorrow will bring...
