Google DNS and OpenDNS can slow down Apple TV streaming

Parallels Desktop 6 for Mac!“The experience of one Mac developer with his new Apple TV box, offers a reminder to the tech-savvy “power user” that Google DNS and OpenDNS may take a serious toll on performance video streaming,” David Morgenstern reports for ZDNet.

“On his blog, Joe Maller wrote that he had a fast Internet connection (15 – 20 Mbps), and so he was shocked when his Apple TV reported that it would be several hours before he could start watching his HD video. The culprit in his case was Google DNS,” Morgenstern reports. “It appears that Google DNS and OpenDNS don’t mix well with the way that distributed video is served up.

  1. This is based off of ONE person’s experience. Definitely not a well proven theory.

    I use OpenDNS at home and my Apple TV always starts TV and Movie rentals within 10 seconds. There is absolutely nothing wrong with OpenDNS from my house.

  2. Appears that the problem arises when Akamai assumes your DNS server is near your location. So it attempts to use the most effective path. Combine that with others who are using universal DNS servers and you get a lot of people using similar longer paths.
