SG Speed Test

To test your current line speed, simply choose a server based on your location, and click its link below. The test may take up to two minutes to complete. For more accurate results, you should turn off any applications that are currently using part of your bandwidth, such as internet audio/video streaming, VoIP, P2P, etc. You may also want to temporarily disable firewall software, and any third party security applications that could block large file downloads and/or prevent redirects (such as Norton Internet Security and Zone Alarm). Priority access, more reliable tests, and longer test history is available to registered users.

Special thanks goes to all that are hosting mirror servers! Testing from different locations helps better understand your connection status. We are still looking for more quality mirrors. If you can donate some bandwidth, it would be greatly appreciated and help improve this free tool for the benefit of all users. To host your own test mirror, please read this.

Test Mirrors Map
Click on a server near you for more information and test links. Double-click to zoom in. Marker colors signify current server load.

Custom Speed Test
You can choose your own test sizes, preferred mirror, and simply click the Start button to initiate your speed test.

Notes:

• Please turn off any applications that may interfere with this test, such as Web accelerators, P2P software, etc.
• JavaScript must be enabled, both for our domain, and the test mirrors you're testing from !
• SG speed tests measure both your downstream and upstream line speed.
• The SG speed test transfers nearly uncompressable data, and displays your transfer rate. In perfect situations, this should be close (~90%) to your advertised/rated line speed.
• Web-based speet tests are just an estimate of the slowest link between you and the test server. Tests are dependent on many factors, such as time of day, congestion on the path at the time, your ISP's backbone/connectivity, your allocated bandwidth, the particular node you're on, the state of the Internet at the time, latency, moon phase ;), etc.
