Umm, brilliant thank you for this.

I ended up with a Dyn / Route53 configuration. We used libcloud to sync everything together. We also added the exported zone to Cloudflare but did not enable it.

We had actually planned for this, but in no way did we ever come close to your in depth testing. The @ Azure issue - thank you for uncovering this for the rest of us.

Can you maybe share how you did the sync between them? Also there are already some tools pulling zone data from Dyn and adding it to Route53? Can you share why did you choose an own sync. (I'm planning to do the same and I'm interested in other's opinions)

We actually wrote a tool to manage this. We define our desired records in a common dsl format, and the tool can interact with various providers to ensure things match the expected state.

We should be open sourcing this rather shortly, so stay tuned.

Sorry, I'm not who you asked, but that is how we are doing it at stack overflow now.
