I have recently been contacted by a company which claims to be able to somehow root the DNS geographically. In other words they would determin the location of the user by IP address & direct them to a hosted version of my site. This may resolve some latency issues & timeouts, plus it may also resolve some security issues. My question is... How will this impact Google's spiders when indexing the site? I assume the spider would also get directed to the nearest hosting server... Could this effect our SERPS in Google? Would it have a postive / negative or neutral effect? Any advice appreciated because i have never heard of this kind of DNS request handling previously.
