Geo-Aware DNS and Rankings?

[arikgub]

I would like to run a geo-aware DNS that will send users to one of the two servers hosting my website - one in the US and the other one in Asia.

Same domain, exactly the same content but different IPs via geo-aware DNS - the geo routing is only to improve speed for a growing Asian audience.

Are there any pitfalls in this approach I should be aware of? Should I expect any negative impact on the rankings? Or may be a positive one, will it help me rank better in Asia? I'd appreciate any advice or head ups.

I don't think it will make a different either way. I'm almost positive Google doesn't take DNS and IP addresses into account when ranking.

What can make a difference in ranking is domain name TLDs if you are targeting a specific language.

Google is very used to sites that use CDN services that work very much the same way. This shouldn't be a problem.
