I agree with the second part - users are more likely to forgive an outage when Netflix is down as well. However, AWS is not as stable as I'd like. It seems the days of targeting 5 9's (99.999%) uptime are long gone. If you have high availability requirements, the cloud providers are a convenient way to get access to multiple datacenters. But, you absolutely must have cross-region failover. Amazon's products and datacenters only have "pretty good" uptime, and I've found their functional uptime is lower than advertised. When a network problem causes Lambda to become unusably impaired, Amazon still considers Lambda to be available.
