Re:Google DNS servers suffer brief traffic hijack

If I have DNS server 10ms away, you can bet your ass (and house) I can expect a smaller latency than from one hosted 6000 kilometres away across an Atlantic ocean and then some.
You should look into "anycast". The Google DNS servers are located all across the globe. For example, I get 60ms from Portugal (just +30ms than I get to my ISP's server). And Google's servers, due to higher use, are much more likely to have the records in cache, reducing the overall latency when compared to a server than needs to issue a recursive query for every less commonly used domains.
