What about caching? Do you need to keep your TTL low to do this? My TTL is set to about 24 hours, so if I have to change IPs I'm assuming that I'd be down for 24 hours. If I set my TTL to, say, 5 minutes then we load our DNS servers more. Is this right? This has been a burning question with me

One specialty DNS service (I'm not affiliated), UltraDNS mentioned to me that they use a TTL set to 5 minutes. Also, they are able to propagate changes thoughout the various zones so that any DNS changes are actually virtually immediately viewable (5 minutes).
