@tastiger sorry for the hassle factor. We use Amazon Cloudfront to edge-cache the release installers which are actually stored in Amazon S3.

After more research, it appears it can take up to 24 hrs for updates to propagate to all edge-cache locations. More detail here if interested: https://aws.amazon.com/premiumsupport/knowledge-center/cloudfront-serving-outdated-content-s3/

Please try downloading the installers again later today and let us know if problems persist.
