Bandwidth Information

Find out how fast your internet connection is. Test the upload and download speed. Results may vary due to other browser activity, downloads, net congestion, etc. To be able to get better results I've included a number of different speed tests on this page. This will give you the opportunity to run different tests and compare the results.

I'm not able to host the available bandwidth testers themself, but only link to them. This is due to bandwidth considerations.
