We tried to launch this morn, but are getting: Launch Failed Unable to launch image ami-89c2d9e0 as the product code 8ED157F9 is not supported for the specified region, instance type and operating system combination. Please contact the vendor for more information. Hide launch log Initiating launch Interface looks different on first, so I think amazon is pulling a fast one again… We are currently down, so any help would be appreciated. -Ben ---

As an update to this thread, the prebuilt devpay AMI’s listed in [our article](https://www.wowza.com/docs/pre-built-amis-amazon-machine-images%28amazon-machine-images%29) are only available with the instance sizes listed within that table.
