TTL does not matter because I am not adding or removing systems from my DNS record. Even during an outage, a request to my domain name will return both the broken and the working load balancers.

I am simply giving a list of servers that can answer a request.. clients know to keep trying till one works. (Which they all do. Try it!)

Basecamp/SignalvsNoise/37signals had an article up on how they used Dyn.coms DNS service to achieve something like this, but I can't seem to find it. They had some nice graphs for when they tested it out.

Edit: My Google skills are poor, but I found it here: https://signalvnoise.com/posts/3857-when-disaster-strikes

Thanks for the -1 on a true statement about my own hosting setup!
