My guess is that it's related to yesterday's problems and just figure that it'll update in a few more hours.
WHEW! Thanx for that update. I was worried. To say I am OBSESSED by those stats is an understatement. I find them very useful. BTW, my daily hits have grown about three-fold in the last 5 months. I want to to grow about an equal multiple by the beginning of next year.
