I don't understand how this is measured. For instance Google Fiber is 3.69 Mbps. For a gigabit internet service, it seems fairly low.

The top number might be the most that Netflix needs to stream a video. The numbers are not important, this is more about variance to each other.

hmm. comcast dropped from 2.17 to 1.63 mbps YOY. awesome. luckily, speedtest.net shows me a lot higher than that... 25mbps, to be precise. Edit: I see Netflix has tweaked their results to use 'Prime Time' readings only. I guess I should retest this evening as well.

I care about my bandwidth to Netflix a lot more than I care about my bandwidth to speedtest.net.

You can test on many different servers, I tested to a server in virginia since I assume it would be a reasonable proxy to ec2 us-east bandwidth.

It looks like this is just measuring the average bitrate that people are streaming at. It won't reflect whether or not someone is capable of watching higher quality streams than Netflix is actually giving them. I don't think their highest quality is more than 6 megabits/sec, and it's only available on certain devices and movies.

Why no latency measurements?

My guess is because latency is not relevant when it comes to streaming videos from Netflix. A consumer will not be able to notice their video took 40 milliseconds longer to start streaming. They will, however, notice when the video stops to buffer every 10-15 minutes because their ISP can't keep up with the throughput.

Would latency affect the non-streaming parts of Netflix, e.g. browsing titles?

Netflix hosts their video servers much closer than ec2's us-east...

False. Speedtest.net gives results in Mbit/s. 25 Mbit/s ≠ 25 Mb/s. 1 Mbit = 0.125 MB

While others have correctly pointed out that 25 Mbits/s does in fact equal 25 Mb/s, (though, I always use Mbits/s, just to eliminate the confusion) - I'd also like to note that bandwidth is always measured in SI Mbits - I.E. 25 Mbits/s of bandwidth is always 25,000,000 bits/second.

Any time you see someone call it out explicitly as 25 Mib/s, double check and see if that's what they actually mean - 90+% of the time it isn't.

The list of speedtest.net servers is public and I don't doubt that Comcast uses it to drive traffic shaping decisions. Speed tests are meaningless except to establish an upper bound on last mile speed. They are not representative of bandwidth to real services like Netflix, YouTube, Dropbox, Steam, etc.

It is a gigabit internet service, but there are also people on the free internet plan which is slower.

I am pretty sure nothing is streamed off of AWS - possibly Cloudfrount , but based on what I know of Netflix use L3 and Akamai heavily.
