CloudFlare offers CNAME option for paid customers. So you can use an enterprise DNS service and only point to CloudFlare via a CNAME record.

When disasters like this happen, a quick DNS change can be a life-saver.

There's no such thing as a quick DNS change.

My startup NameTerrific can support instantaneous DNS updates in a geo-redundant Anycast infrastructure. As long as your TTL is sufficiently low (<300), the impact is quite limited as propagation time is negligible at NameTerrific.

EDIT: Sorry guys. We got some issues with a gem after installing the recently updated ruby2.0.0p0. The unicorn workers were timing out. TerrificDNS is completely unaffected and the site is already running again.

"We're sorry, but something went wrong."

If and only if the site's end users and their software fully respects TTL. A lot don't, especially shitty mobile networks and web browsers.

From my experience with DNS for a large site over the last years, a lot of ISPs do not respect your TTL and have their own TTL (often 24h).

"502 Bad Gateway

nginx/1.2.7"

It's up now. Please see parent for explanation. Sorry!

Hopefully the back-end is not running Ruby. ;-)

The back-end is AWS Route53, it seems.

Well, we have already soft launched our own TerrificDNS Anycast and it has replaced the Route 53 solution. TerrificDNS platform is running on Redis + PowerDNS.

Terrific.

Nameterrific is down. https://www.nameterrific.com/

You should probably put the same amount of effort into your web hosting infrastructure http://imgur.com/ok5lfml

Would love some details on how to do this, I've been a (business) CF customer for a while now and have never seen this service and I haven't turned up anything googling/scouring their website for it just now.

Details much appreciated!

EDIT: Spoke too soon: https://support.cloudflare.com/entries/22054357-how-do-i-do-... shame it's so convoluted

That is the first time i have heard this as well. Thanks for the Link.

Yup, this CNAME service just allowed me to make a quick update to DNS and get us back up. We will probably need to automate this in the future.

Yep, this is definitely something I'll do in the future and I guess it was my fault for trusting a single service... even one that is designed around keep your site up/redundant.
