Describe what you would like us to do:
Include the ap-southeast-6 region for cloud and coreos image deployments in Amazon EC2.
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html

To Enable a region:
Sign in to the AWS Management Console.
In the upper right corner of the console, choose your account name or number and then choose My Account.
In the AWS Regions section, next to the name of the Region that you want to enable, choose Enable.
In the dialog box, review the informational text and choose Enable Region.
Wait until the Region is ready to use.

We would like to get AWS public access enabled for this region. Please use the following command:
"aws ec2 disable-image-block-public-access --region ap-southeast-6"

We would also like the "Public AMIs" quota level to be set to a minimum value. The quota codes can be viewed using the below command:
"aws service-quotas list-service-quotas --service-code=ec2 --quota-code=L-0E3CBAB9 --region=ap-southeast-6"

Let's make sure to adjust the quota to match the other regions if necessary. If the current quota is less than 1000, let's bump it to at least 1000 with the following request:
"aws service-quotas request-service-quota-increase --service-code=ec2 --quota-code=L-0E3CBAB9 --desired-value 1000.00 --region=ap-southeast-6"

When do you need this to be done by? (YYYY/MM/DD)
Preferably before our next FCOS release.
