Basically, I want all the traffic to go to one server while the other reboots. Here's the environment:

Two or more VPS servers.
Same datacenter, but no internal ip or lan, and no shared ip.

I was thinking of this:

Update Dynanmic DNS settings to takeout server #1...
   redirecting all traffic to server #2.
Reboot server #1.
Update Dynamic DNS settings after reboot to allow #1 and #2 servers.

Is this a misuse of Dynamic DNS?

    Because of DNS caching this is probably not going to work very well. I would suggest load balancing the two servers so that requests are directed to a VIP and can be handled by whichever server is available. – joeqwerty Jul 19 '13 at 17:10

We did not have much luck with this. In your described scenario our clients did not reliably fail over using the method you describe.

I recommend a load balancer between the two servers so that requests are directed to a VIP and can be handled by whichever server is available.
