In May, Netflix announced Fast.com, a website where users could quickly and simply check their internet connection speed. The site uses Netflix's servers and technology to give people an instant look at their current internet speed. The site quickly became popular, and Netflix has now released the FAST Speed Test app for mobile devices.

fastspeedtest
Once opened, the app instantly begins giving users a reading of their internet speed. Once the test is fully complete, results can be checked against results from SpeedTest.net, another popular internet speed checking solution. Both the website and app utilize simple, minimalist designs, with the service's logo and download speed tracker taking up much of the space. The refresh button, the lone button in the app, allows users to restart the test.

On its blog, Netflix's Sergey Fedorov and Ellen Livengood explained that FAST only displays download speeds because thats how most users interact with the internet, whether it be streaming video or loading webpages.

To test speed, the app and website undergoes several download tests using Netflix's technology and services, including downloading chunks of a 25 MB video file through "a variable number of parallel connections." Fedorov and Livengood go into technical detail about how the service works on the company's tech blog.

FAST Speed Test is available in the App Store for free [Direct Link]

The only thing I can't keep thinking about is that they probably stole some guy's ownership of the website. There's no way nobody registered fast.com previously.
I don't think you know how domain name registration works.

If it belonged to someone else before, Netflix probably paid a good amount to get the domain. It's not something that can be "stolen".

I deleted it as soon as I found out that this app works just like the website. I just don't want to clutter my phone with another app. The funny thing is that, the service provides recommendation to a link to compare it to speedtest.net. It's kinda like promoting the competition, it feels like having a yahoo search or bing search link right on google homepage. :D
I suspect the whole point of this app, and the point of using live Netflix servers and streaming tech, is to expose traffic shaping by ISPs. I've previously had an ISP which throttled pretty much everything except speedtest.net. Comparing the results of two apps will help shame the shapers.

I think you've confused the word "stole" with "purchased by backing a dump truck of money up to his house."

Hmm. I will continue using my pro Speedtest app. It is more popular.

Update: This site only provides download speed test, not upload speed test.
But Speedtest app does not test against Netflix servers, so you will never find out if your provider is throttling your connection when streaming from Netflix - unfortunately common practice from providers that have their own streaming service since that makes them look better. This is the purpose of this app, that's why upload is not included.

EDIT: By "stole", what I mean is that if the owner of the site was a nobody, they are no match against a giant multi-billion company like Netflix. They could have easily just caused a "transaction error" or "termination for copyrighted content". I don't think that's what happened, but I'm just stating the possibility.
