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. This can be Apple TV or YouTube.”

Morgenstern reports, “After switching from Google DNS, Maller said his Apple TV rentals were ready in less than 30 seconds.”

  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.

    Happens all the time. I’ve cancelled my Rogers Hi-speed internet thinking that it was the culprit. This explains a lot. I’ve been a fan of Google from the beginning but this sort of thing leaves much to be desired. It seems Google services are introduced before they’re ready and beta is just an excuse for not a lot of what they do right.

    Can anyone suggest how to simply solve this issue?

    This probably isn’t Google’s fault. It’s probably just that their DNS servers ( and are in Cali. Some content distribution services tell different DNS’s different IP’s so you get the closest server. So, if you’re in North Carolina, and Google DNS has the server closest to Mountain View, you’re going to get content from some server in Cali, rather than the closest one. Not Google’s problem.

  5. My ISP is Comcast in Central Indiana. I use OpenDNS at home and the Apple TV has no problem streaming from Netflix.

    I cannot comment on streaming from Apple as I do not rent from the iTunes store. Movie trailers seem to stream normally.
