How CDNs and Alternative DNS Services Combine For Higher Latency
The_PHP_Jedi writes "Alternative DNS services, such as OpenDNS and Google Public DNS, are used to bypass the sluggishness often associated with local ISP DNS servers. However, as more websites, particularly smaller ones, use content distribution networks via embedded ads, widgets, and other assets, the effectiveness of non-ISP DNS servers may be undermined. Why? Because CDNs rely on the location of a user's DNS server to determine the closest server with the hosted content. Sajal Kayan published a series of test results which demonstrates the difference, and also provided the Python script used so you can test which is the most effective DNS service for your own Internet connection."
For one, because they're deliberately abusing the Open moniker. They also do not provide an ad-free DNS service, unlike for example Google's DNS server. Furthermore, they redirect www.google.com through OpenDNS servers. Last but not least, to change the configuration (e.g. the Google redirection or the NXDOMAIN highjacking), you have to get an account and always log in. For DNS. Are you kidding me?
I don't give a shit if you use OpenDNS or not. If you like their censorship features then that is great, use what works for you.
What I do give a shit about is people recommending OpenDNS as a good alternative for ISP DNS servers in discussions about NXDOMAIN fuckery. They are about the absolute last alternative DNS provider you should choose if NXDOMAIN is important to you. Just about any of the dozens of other free DNS servers doesn't require you to do retarded shit like use DynamDNS just to get standards compliant DNS results, recommending OpenDNS is irresponsible at best.
Seriously, just because they have "Open" in their name, doesn't mean they are good.

>. Unfortunately the old guard of DNS (Vixie, et al) are not supporting it because they fear it raises insurmountable privacy concerns.
Old guard? You'll find end users are also very much concerned with privacy. Rewriting the DNS spec solely for CDNs is ridiculous. Want location services in web broswer? Add it to http. Let the browser makers figure out the implemention.
Not to mention, there's nothing open about your service. Its simply free. There's nothing open source about it and you openly violate the DNS spec with your typo domain crap. Sorry, the internet doesnt need "open" dns to ruin dns. You've done enough already. Thankfully, google offers free dns at 8.8.8.8.
