So then do you get full line speed results from the test?

Interesting though, from watching tcpdump while doing a speedtest, I’m seeing it hit BOTH of our local on-net Netflix appliances (over IPv6).

Netflix uses a lot of EC2 stuff, so you’re not necessarily hitting their “cache” when you pull up their website.

Very inaccurate too.
I get 160Mbps results on a 10Gbps connection.
This is with a path to Netflix that pretty much sits in LA.
So I am assuming I hit their CDN in LA all the time.
Not sure where their speed test web app is located.

This could be useful from a residential last mile customer point of view, to expose ISPs which have good peering/low congestion tospeedtest.net <http://speedtest.net/>but might have less than optimal routing to Netflix. Or an ISP that is flat topping the traffic charts on an N x 10GbE link to netflix somewhere in the intermediate path.

Some people will see radically different results from speetest vs this new Netflix test during peak evening hours. On Wed, May 18, 2016 at 3:24 PM, Nate Burke <n...@blastcomm.com <mailto:n...@blastcomm.com>> wrote:

    Utility from netflix. Torching it looks like it opens 3 HTTPS
    connections to 3 different IP Addresses to run the test.  Only
    reports download speed, no Latency or Upload.
