Tuesdays and Wednesdays are traditionally my best earning days of the week however yesterday was trully diabolical being down across all metrics by almost 40%...that's not an acceptable fluctuation by anyone's standards.
I find it quite coincidental that at the same time as a bad earnings' day that many in the Search forum noticed a massive drop in Gbot activity.
Supposedly they're not connected however has G had some kind of outtage resulting in AdSense data loss?
