Just because it's a global site doesn't mean the traffic is distributed uniformly across the day. Certain regions are going to have higher traffic during business hours. I'd guess their off hours are somewhere around 6pm PST when North / South America has stopped working, Europe / Africa is asleep, and India is just waking up.
