I used to do infrastructure on physical hardware, and we'd go years without an outage sometimes (generators in the datacenter, diesel fuel contracts, redundant fiber providers using BGP). Doing it in the cloud is harder, because you're at the mercy of the provider when things go south, and you have no transparency into why it went wrong except what they're willing to publish. Why did it happen? Will it happen again?

I mean, you can argue that the cloud is better. But how often is Heroku and AWS down? About the same as physical providers (I concede S3 is pretty solid though).
