I’ve been monitoring google DNS for a few months now, just as a latency/connectivity test from our head quarters. I noticed a big drop in the round trip time to 126.96.36.199 on May 7th. A ping of around 10-20 is typical from the UK to Europe so would suggest that until recently, Google DNS had no POP’s in the UK and that it was based out of Europe somewhere. This link shows a number of European locations in Germany, the Netherlands, and Belgium. The drop down to 2ms suggests that there is now a POP located in the UK – London perhaps. For anyone that continues to use their ISP’s (flaky?) DNS service, this reduced latency might be enough to persuade you to start using google DNS.
