"The urban legend that DNS-based load balancing depends on TTLs (it doesn’t)"

So whats the solution? We are using AWS ALB/ELB and it states in docs, that we should have low TTL, and it makes sense. Servers behind LB scale up and down. What is the option B?

In fact, if you use Route 53 with an alias to an ELB, the TTL is hard-coded at 60s -- it is not even configurable. If it were, we'd follow the practice of lowering it prior to changes, and raising again once things or stable, but as it is, that's not an option (moving DNS off AWS would be a hard sell, not cause it's terribly hard but afamic, there's not really any value to doing it).
