Also, it'd be a great public service to publish the results. Even if it's just enabled for a day per year or so the results would probably appreciated by many. And you could always sell your altruism as the need to continually monitor the situation :)
Here's the math for expected number of tries if half of the servers are offline. (It's a hypergeometric distribution but I couldn't find a closed formula)
E(2 server) = 1 * 1/2 + 2 * 1/2 = 1.5
E(4 server) = 1 * 2/4 + 2 * 2/4 * 2/3 + 3 * 2/4 * 1/3 = 1.67
E(8 server) = 1 * 4/8 + 2 * 4/8 * 4/7 + 3 * 4/8 * 3/7 * 4/6 + 4 * 4/8 * 3/7 * 2/6 *4/5 = 1.73
I think I measured Cloudflare's performance and chose it over Google because it was consistently faster. If the stack-stackers are reading, I'd love to hear why they didn't make the list.

Do you think after the Dyn outage everyones sysadmins are running round adding redundancy, too worried to trust the uptime of their site in the hands of just CloudFlare?

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.
Netflix have a tool for this as well https://github.com/Netflix/denominator
Denominator is not actively developed: https://github.com/Netflix/denominator/issues/374 Last commit of substance was in Sept 2015.

I have not looked at this particular commit history, but I want to argue against the notion that no fresh commits must mean that a project is abandoned. Some stuff is just mostly finished after some point.
So... I wouldn't invest time in it unless you want to take over stewardship (no one else has offered in the last 7 months).
Very good analysis of SO and a smart move to roll this out _before_ a new DNS outage!
I'm currently working on a tool [1] that can help with checking if all your different providers are 'in sync' and responding with the same answers. Setups like these are only to grow more common as people realise a single DNS provider is a SPOF of its own.

If you could have a unified API that would create the records on multiple providers that would be money, it's just that you'd lose out on some things like Route 53 health checking, etc.
Hurricane Electric supports this but most of the providers mentioned in this article do not.

+1 - I am also very interested why they chose to switch out from CloudFlare for both their DNS and their CDN and over to Fastly. Nick Craver did a write up where they specifically mentioned [1] Cloudflare for both their DNS and CDN.
