It is possible to use Cloudflare DNS on Shifter sites after making a few changes to the default settings from the Cloudflare Dashboard.

It's important to disable their Proxy feature as Shifter provides CDN services through Amazon Web Services and Amazon's CloudFlare which it is built on.

Disabling Cloudflare Proxy

Click Orange Cloud ("DNS and HTTP Proxy (CDN)") and turn it to Grey Cloud ("DNS only") when adding records for bypassing Cloudflare on existing DNS records.
