RE: Speed up DNS resolution
Patrick, you have chosen a TTL of 1 day:

RE: Speed up DNS resolution
I had it at 3 hours and bumped it up to one day because of a surge in traffic with the Google Page Speed Service launch and I wanted to keep my DNS queries well under my limit for my DNS Made Easy account :-)
The server is on a static IP and I can easily move that IP to another physical box if there are any production problems. If my hosting site goes down it will take me a while to bring it up somewhere else so 1 day is reasonable for my specific needs. |

I was not able to find if they use some kind of distributed DNS (SE Asia region has too long DNS look up). I found out that Cloudflare has free globally distributed DNS network. |

RE: Speed up DNS resolution
I'd recommend first installing a RUM monitoring solution like Soasta's mPulse that will report the DNS times that your users are seeing. Then if you experiment with a change you can see what the actual impact was (if any). If you do experiment, make sure to give it several days for the various DNS caches to update (the authoratative DNS provider switch sometimes takes a few days to propagate).
