I just updated my comment.
I don't keep my names at 5 seconds, usually I keep them at 1800. But when I did a server move recently it was great that I could lower it to 5 seconds for the change. Most registrars don't have this support, and if I hosted my own service it would be just as hard to make quick server changes.
- aeden 16y agoYeah, I can see the value in that. Right now the minimum can be 1 minute at DNSimple, which I figure is low enough for most cases. :-)
- davidu 16y agoThere are downsides to very low TTLs. I'd advise against them. Best practice is to set a high TTL, and as you plan to make a migration that involves DNS, set a lower TTL so that when you make the change it propagates quickly. When done and all is stable, raise your TTL again. The longer your record is cached, the better off you are.
