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.
