If your web host goes down or you have a dispute you can then use your trusty DNS management panel (at your 3rd party DNS host) to point to a different IP and within a few minutes your URL is resolving to a site you have setup at a different host.

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 :)
