comment rsync: can't get rid of password prompt
There are instances where we must backup or otherwise automate file transfers from systems which are legacy, or for whatever reason do not support SSH keys.

Maybe the 3 hours is referring to a nameserver change as opposed to a record change.

Indeed on the charges – for example, dnsmadeeasy.com charges $29.99 / year for enterprise DNS that includes 5 million queries per month, then it's something like $1.85/million-queries/month after that.

How else would you have IP failover? Even if IP x.x.x.x is setup as a routing gateway that determines which server delivers the requested content, if x.x.x.x has hardware failure you'll want something else to take its place immediately, right?

Can you elaborate? If I ping a domain with a 60 second TTL and switch the A record I see the new IP within 60 seconds.

Thanks for the detailed info. Regarding the ISP's DNS resolvers and my own experience: in this instance the domain is registered @ Network Solutions where the lowest TTL allowed is 1 hour. @ dnsmadeeasy.com we now have it set to 60 seconds at which point the site will point to a backup server in the event the cloud it's on has hardware failure. I've done this on one other site and had fantastic results; when the primary cloud failed, users (and all of the test machines and phones I've tried it on) immediately saw the backup site. Hopefully it continues to work this well.
