If you know you need to make to your network, you can set TTLs to be lower, several days in advance. Problem solved.
(It's true that some crappy DNS resolvers don't honor TTLs, so you'll need to retain control of old servers for at least several days afterwards, to set up some automagic forwarding, receive mail from senders who haven't caught up with new MX records, etc. But none of this should be too difficult.)
- brk 18y agoTrue, but if you have a reasonably popular site SOMEONE has always broken DNS TTL's along the way. I've been through this more times than I can count... If your site is still small/early, it's less of an issue.
- maw 18y agoRight. So, like I said, you need to control the old servers for at least a few days after the cutoff date.
