Okay, we now have our own IP address. All users should not have seen no downtime as I had the TTL on the zone set to 1 minute and I left the old server running for 1 minute. Along with this, I have removed support for the legacy domain http://journal.insanityspeaks.com/ This URL now sends you to a page the redirects you to http://www.insanejournal.com/.
So far everything looks to have moved pretty damn smooth. I am going to wait a day, then bump the TTL on the zone back up to something sane (just incase I have to move back).
After it is fully tested, we will be able to support custom domains (such as pointing your.domain.tld to your journal). This combined with S2, which is coming along quite nicely. Which will allow you a totally customized journaling experience.
