how is it that amazon.com itself is never, ever, impacted?

edit: so basically, the businesses suffering outages (heroku, netflix, etc) don't value uptime to the same extent that amazon does. they got what they paid for.

Amazon.com does not run on the same EC2 that you and I use. It runs on a nearly identical system that is isolated and private to Amazon. I wouldn't be surprised if they were in entirely different physical locations.

This outage only affected us-east-1. Considering an Amazon.com outage would cost them $51k in lost sales every minute, I seriously doubt they put all their eggs (servers, that is) in one basket.
