Can I use CDN2 internally on non-public websites (such as locked down intranets)?
No, not yet. But we’re adding support for this. Right now, the services “pings” back to your site to publish your Drupal video. We’re making it so that you can optionally “pull” via a cron or cron service. Right now your site or sites must be on a publicly available URL in order for the service to function properly.
