Beta Testing a New Open-Source Speed Test
Today we’re kicking off the public beta for a new speed test that we plan to make available as open source software, so others can use it to create their own speed test, see how it works, or improve the code. Starting today, any Xfinity Internet customer can try out the new tool and provide feedback at http://speedtestbeta.xfinity.com.
As with any open source project, we’re looking forward to other folks in the technical community improving the code, and adapting it for their own use. To move that process forward, we’ll be working with Princeton University to host a speed test hackathon in November, bringing together contributors from a range of institutions and organizations. We plan to make the code available on our GitHub page at the conclusion of the beta or just before the hackathon, whichever comes first.
Speed tests are invaluable. They help us confirm that we’re delivering fast Internet speeds and can help customers diagnose and detect issues that may be impacting performance such as Wi-Fi access point placement.
Like many ISPs, we offer a third-party-powered speed test tool. That tool performs exceptionally well, and millions of people use it regularly.
For this speed test, however, we are testing a new tool to address several interesting technical challenges:
We will also continue to work with measurement researchers from around the world – many of whom we have gotten to know well via the Comcast Innovation Fund – to study the resulting measurement data that the testing tool returns.
The beta site is live. Users can provide feedback here. We’ll be back with more information on the hackathon, open source repository, and other developments as our beta testing progresses.
