Right. Downtime (or perception of downtime) is bad for business, so AWS is surely working to improve reliability to avoid more black eyes on their uptime. But at the same time, an AWS customer might be considering multi-region functionality in AWS to protect themselves ... from AWS making a mistake.
As a customer, it's unclear what the right approach is. Invest more with your vendor who caused the problem in the first place, or trust that they'll improve uptime?
