As an admin, I use low TTLs when I do some major DNS maintenance. I wouldn't mind upping the TTLs after, but... what about if I need to do some emergency maintenance, like the IPs on a load balancer change and I can't get the old IPs back? I don't want to wait an hour for clients to pick up the new IP.
It would be great if there were some reverse notification to let revolvers know to refresh their caches.
