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 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┬álink 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.
