No. We have never had a production outage of the service to date, but more importantly the way we designed our deployment architecture has a fallback mechanism built-in: the existing AutoScalingGroup your application was using before. So even if the CloudOptimo service was offline, the normal AutoScalingGroup scaling thresholds will scale the application up or down. It would use On-Demand instances, so costs would return to what you were paying before, but application availability and performance would not be affected. We do recommend that you set these scaling parameters so that they do not conflict with normal CloudOptimo operation, such as scaling up and down at a higher CPU level than the CloudOptimo CPU settings, and/or only kick in after a longer time period of meeting the CPU criteria. Otherwise the two scaling mechanisms will fight with each other somewhat and you will lose some of the cost-savings and diversification CloudOptimo provides.
