Re: When will STM be available in AWS South America region. If at all?
My understanding is that it will be available with an upcoming update to the underlying operating system of the STM Virtual Appliance. The Sydney and Sao Paulo zones were established by Amazon without backwards support for the kernel version we are currently running on the AMI's.
As for time frames, there are no committed time frames for the release, but I can tell you it is on the roadmap...
