One thing to consider is that we currently stream S3 downloads via our Rails app.
On a GFE VPN connection it can take 20+ minutes to download a 4G file.
Investigate whether this architecture holds open a db connection for that long, and consider instead signing the S3 request and simply redirecting to the S3 URL directly (bypassing efolder and downloading directly from S3).
