We've experienced around a 15% drop in traffic, but based on the hourly pattern it seems like there is a lot of switching between data sets. In other words we're down 20% for two hours then up 10% in the next hour,then back down 20% for a couple more hours.

I'm comparing week-over-week hourly traffic patterns, which generally don't move more than around 2% each week.
