S3 bucket URLs problem

[epackorigan]

I am having problems with deploying with the s3 URL as specified in the templates today.

If I am reading https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingBucket.html#access-bucket-intro correctly, the style of URL is valid only if the client and the bucket are in N.Virginia if the regios were created before a certain date. In addition, it appears that some of the behavior will change also later this year. It looks like the bucket URL should be <bucketname>.s3.<region>.amazonaws.com.

(assuming that the region would end up being a parameter in the various stacks)
