Bert, I can't remember exactly where I saw the original reference about Amazon, but I saw this on HIStalk:
From Professor Paul MD: ?Re: Amazon cloud downtime. For those who didn?t know, their northern Virginia data center that hosts EC2 and RDS services went down hard for 24 hours last week and didn?t recover all volumes until late Sunday. A small company that apparently does ECG monitoring repeatedly begged for help on Amazon?s public online forum, bringing up good points on what to consider when hosting health apps on the cloud."
