Netflix Launches Fast.com To Show How Fast Your Internet Connection Really Is (venturebeat.com)

Paul Sawers, writing for VentureBeat (condensed): Netflix really wants to show you how fast (or slow) your Internet connection is, and to do so it has launched a new website at Fast.com that conveys the real-time speed of your connection to the Web. It's designed to give people "greater insight and control of their Internet service." Netflix said it was for: Providing a website featuring non-downloadable software for testing and analyzing the speed of a user's Internet connection, as well as downloadable computer software for testing and analyzing the speed of a user's Internet connection.Compared to Speedtest.net, Fast.com doesn't offer any details on how fast is your upload speeds, what's the ping time, and any detail on location and ISP. However, it's seemingly faster, and automatically detects your download speeds when you visit the website.

Works great

No Flash, no Silverlight, got my cable download speed accurately.

Here's another good one that doesn't require Flash or Silverlight but gives a lot more details: https://www.voipreview.org/spe...

Selective throttling

[JustNiz]

I've long held a theory that my ISP (Cox) is limiting bandwidth selectively by site, and that they make all the benchmark sites wide open, but throttle others, like netflix.
It seems they have already added fast.com to their "Do not throttle" list but not added Netflix.

I'm pretty sure Google's Public DNS uses anycast IP addresses. Meaning you'll probably still get the closest server in the results. A lot of CDNs do the same thing.

Never stop never stopping

Could not reach our servers to perform the test. You may not be connected to the internet

If I wasn't connected to the internet, I wouldn't see the page indicating I may not be connected to the internet.

Who needs a test when you have real-life app data?

[Cajun Hell]

If this is primarily intended for Netflix users, then why not just have the client measure the speed of actual live use cases? Some games have an option to show frames per second; your streaming player could have an option that shows bits per second.

Your burst speed means nothing. I was going well beyond my DSL cap if I only cared about burst speed, the EFFECTIVE speed is considerably lower. Any speed test site is only as good as the infrastructure, and once it's popular, ISPs will unthrottle connections to that service, much like they have agreed to do with netflix, and it becomes speedtest.net version 2. If you want to test your speed to the internet, reliably, you have 1 choice. Host a webserver yourself somewhere, and upload files to it. That's literally the only test you can trust.

Browsers and Bittorrent clients report download speeds in kilobytes or megabytes per second, this site reports download speed in megabits per second. 1 megabyte per second is around 8 to 9 megabits per second given overheads. Your 5 megabit/s line will reflect in the browser as 600 kilobytes per second, so the site is confirming your experiences.

Download are done from nflxvideo.ne

[JcMorin]

I did a quick lookup and the download are made from: https://ipv4_1-cxl0-c273.1.nyc....... I believe this is the same domain as the real video so that would make it harder to block on "fast.com" since data are not downloaded from that domain name.
