Dnsyo – A DNS propogation tester

[Looks like a handy little tool if you’re in the website business][link], and it even has a pithy one-line description:

>In short, it’s nslookup, if nslookup queried over 1500 servers and collated their results.

Bonus points for being open source and installable via `pip`.

Google DNS Will Probably Be Fine, Guys

I have a feeling [Kottke’s analysis][kottke] is pretty spot-on: every tenth of a second longer a site takes to load, Google is losing revenue from ads. That might seem nuts to you or I, but Google isn’t exactly in the same ballpark, scale-wise, the stuff you and I work on:

>Half a second delay caused a 20% drop in traffic. Half a second delay killed user satisfaction.

For the Google behemoth .5 seconds is a _serious_ problem, and with [Google DNS][dns] they’re trying to whittle that down as much as possible. Do I trust them? Not really. Do I need to? Not really. I can change my DNS whenever I want, and so can you, and Google’s DNS privacy policy seems, [as Gruber put it][gruber], utterly reasonable.
