I was running a mailserver in a network where OpenDNS was the default. Outgoing e-mail where the ___domain-name was misspelled would linger in the queue for five days, instead of failing immediately, while the SMTP server attempted to deliver to OpenDNS' catch-all host. Apparently, if there isn't a MX record, it's standard to attempt delivery to the A record.
I politely disagree and do not think David spread any FUD, but rather shared his opinion where other techies would see it- here on HN. Switching services not because you think one or the other is better for your needs, but only because you don't agree with the CEO's views/actions is a bit thick IMO. I might not think highly of certain things Steve Jobs does but that doesn't mean I'm switching to Windows 7..
When you say that your service, which intercepts and manipulates requests to get ad dollars, is better than their service, which does not --- for the sole reason that their service is owned by an ad company --- you are coming pretty close to objectively spreading FUD.
Pretty straightforward (-h tests a single A record, -z, the default, tests random labels under a zone).
OpenDNS was faster than Google for me, but slower than my own ISP. However, the numbers are under the noise floor; Google DNS is plenty fast, and bound to be more reliable than your ISP. It also doesn't break the DNS like OpenDNS does.
My point isn't that I know which is faster, but that it's really easy to just test for yourself.
The irony here is pretty rich. You don't do it, although your privacy says you might do it for as long as the account is open. Meanwhile, Google (a) can't do it, and (b) specifically states they won't do it in their privacy policy.
But Google's the one we should be worried about.
I didn't give a crap about the redirector until you started making privacy vis a vis Google DNS an issue on Hacker News.
You have to setup every IP you might make a query from as a "network", do you not? How else would they know you're the one making the DNS query? It's not like a Cookie header is sent via DNS.
