I'm assuming OP means cloud-based load balancers (listening on public ips). Some providers scale load balancers pretty often depending on traffic which can result in a set of new IPs.

Being specific: AWS load balancers use a 60 second DNS TTL. I think the burden of proof is on TFA to explain why AWS is following an "urban legend" (to use TFA's words). I'm not convinced by what is written here. This seems like a reasonable use case by AWS.
