Speed Test

Test your download, upload and latency from a mobile phone up to optical fiber, and everything between. This test is pure HTML5

This test requires your browser's full attention for accurate results. Run the test when your network is quiet, and don't switch to other applications or change browser tabs during the test. A few Windows security and privacy software packages can block the test or slow the browser.

Welcome to the speed test that tests internet speed not just speed to your ISP.
  • A complete test takes less than 45 seconds
  • If you switch tabs during the test, it will stop (blame the browser!).
  • Past tests will show up in this space, so start building your history.
  • We test more than just top speed.

The TL;DR

This test needs a modern (recent) browser. If it hangs under Windows, please temporarily disable any browser extentions or security software that is likely to be a culprit. If you find windows add-ons that use excessive CPU during the test, or break the test, please please tell us about it. There is a FAQ on error numbers that includes other tips. Please wait for the test to finish, and do not switch browser tabs. The results button will show you how your result compares to others from your ISP. If it works well for you, please tell other people.

News: Leo Laporte recommended this test over others on 19th July, on his weekly live show The Tech Guy. Thanks Leo!

What is a speed test?

A speed test checks the maximum speed of your connection to a remote server on the internet.

This test runs in your browser. It does a multiple stream download and upload to servers it determines may be closest to your location. The test should take no longer than one minute to complete. Speeds are quoted in megabits per second (1 million bits per second) or kilobits per second (1000 bits per second) of data.

The speed test attempts to take your network connection to its maximum speed. This can be limited by several factors including the distance to the test servers, the operating system in use, the traffic en-route, and of course any congestion or wiring problems close to your location.

The servers are dedicated to speed testing and monitored for performance. They are currently capable of running from 300 megabit for the smaller servers to over 2 gigabit for the faster servers. Generally the ultimate speed limit is not the server speed but the distance to the server. The closer to the server the higher speeds can be obtained by the client operating system.

About geo-location

The geo-location function - that button at the end of the row - allows you to store a location (long/lat) along with your speed result. This information is NOT shared with third parties. It will be used only to build fully anonymised speed maps. You can delete the location from our database by clicking the button again (green indicates a fix for your IP address is stored).

What is a good Ping?

Ideal ping would be less than 1 millisecond. Since the laws of physics dictate that the speed of light in a vacuum is about 186 miles per millisecond, one can calculate the absolute minimum latency for any point to point link.

Cellphone data and Satellite networks can have very high ping time, although 4G can be competitive with ADSL/Cable, ping on 3G and GPRS can be 500 milliseconds or more.

Why is this the best speed test?

There are a wide variety of speed tests. Java, Flash, HTML5 with nifty graphics. ISP branded tests. Why do we feel this is the best?

  • We have the pedigree. 15 years ago we launched the very first popular broadband speed test. It was a Java applet and did a simple staged download and upload. Last time we checked it had logged over 150 million tests. One of the first ISPs to donate bandwidth was a company called Speakeasy. The traffic must have made an impression on them because a few years later the CEO quit to start .. Ookla aka. speedtest.net.
  • This is the worlds first multi-stream HTML5 speed test. Multi-stream testing overcomes the need for the speed test server to be physically very close to your location. It also represents the modern usage pattern: someone is streaming netflix, a console is downloading a game patch, a VOIP or Skype call is taking place. Of course if you want single stream testing you can set that option in the handy preferences panel.
  • This test does not require highly insecure and annoying (update? again!?) Flash plug-ins or Java installs, nor does it require installation of an app. All your results, from any device, are together.
  • The test works consistently as possible across all modern browsers: Kindles, Playstation4, SmartTVs, Linux, iPhones, Android, FreeBSD and more run the test daily.
  • Wide range of operating conditions: tuned to work accurately over proxy driven satellite links, over laggy phone links - yet in the same 30s to 60s run time it will also measure gigabit capable connections.
  • Your entire test history is kept for your use even if you are not a registered member. Members can delete their tests and the data is actually, really, gone.
  • We do not have an interest in making ISPs look good! All test servers are located OUTSIDE your ISP in amazon and google data centers, the same ones that netflix and youtube use.
  • Your data is private. We collect data in order to present anonymized statistics but do NOT send it outside astrabalservice.ru or to your ISP. If that should ever change, it will be clearly indicated and opt-out will be available.
  • This test does not piggy back a CDN (content delivery network) with an impressive list of cities but dodgy geo-location and shared servers. All test servers are dedicated to testing, are monitored, and are capable of multiples of the bandwdth actually required. If the servers get close to any capacity cap then the number of people per minute testing is throttled to keep results clean.
  • We regularly log gigabit results from well connected research and corporate IP addresses using average PCs and browsers.
  • The test is being fine tuned by ISP customers (members of this site). Our feedback forum is public, please use it to raise any concerns, or ask anything.
