Not all abandon sales are a loss for Amazon. Many customers will simply just com back and buy another day because they don't know about the competition.

Given their annual revenues of $60B and they were down for ~ 20-25 minutes. So they must have lost ~$3M in revenues during entire downtime.

P.S. Wild guess. No idea about how much sale do they make during peak hours.

I was told varying different numbers at the time I joined. I'd be curious to know as well.
