Download of docker client returns 403 Forbidden html

Issue: Bug
OS: MacOSX Sierra 10.12.6
App version: docker-17.03.0-ce.

When I try to download the Docker Linux binary tarfile and try to untar it, I get an error. I end up download an HTML page that shows a 403 Forbidden error page.

Steps to reproduce:

curl -sLO https://get.docker.com/builds/Linux/x86_64/docker-17.03.0-ce.tgz
tar -xz -C /tmp -f docker-17.03.0-ce.tgz

tar: Unrecognized archive format
tar: Error exit delayed from previous errors.

catting the file gives me:

cat docker-17.03.0-ce.tgz
