I don't see what's particularly interesting about this. This is a pretty standard technique.

I didn't realize that anyone still used loadbalancers without liveness testing (a superset of this capability), let alone with this capability.

At first glance it seems to be the same as Heroku's Preboot functionality.

So before this your app would be down every time you deployed? That's nuts.
