..and we've had 100% uptime in our short run so far. Our systems are highly redundant and as decoupled as possible. Still, I wouldn't for one second claim that I, or anyone else, could do better than AWS on reliability.
AWS does a great job on reliability. I do think EBS is a terrible technology that should die in a fiery pit, but they do a damn good job of keeping everything up.
If they really do believe their 99.9999% claim, I'd love to see them make a bet. How about Reddit gets $1M if they move and it falls below that?
