Is Google DNS a Myth?

Google public DNS resolving services on IP addresses 8.8.8.8 and 8.8.4.4 was sold as being a faster solution for users, since caching could occur on a massive scale, but is it just a statistics gathering exercise for Google?

Using NameBench (http://code.google.com/p/namebench/), and running the test, it looks as if Google DNS is actually slower than local services, and popular global ones:

I've often used ZoneCheck to test if DNS is set up correctly, but it doesn't give an indication of performance,
for that, I'd recommend https://www.ultratools.com/tools/dnsHostingSpeedResult - Check for "A" record response, where you should aim to get a response time of 50ms or less.

Here is a speed check of this blog, which is hosted by Google.

.VE Domains down

As of 3 PM GMT, all Venezuelan domains (.ve) appear to have gone down. It does appear that the sole nameserver responsible for .com.ve is unresponsive:

nslookup -q=ns com.ve

Server:  my.router

Address:  192.168.1.1

        primary name server = ns1.nic.ve

        responsible mail addr = hostmaster.nic.ve

        refresh = 900 (15 mins)

        retry   = 300 (5 mins)
