Speed.io is a modern DSL speed test to analyze your broadband internet access. If you find that your internet connection is too slow or you are
just curious how fast it really is - speed.io is a perfect tool for a fast speed check - worldwide.


Speed.io measures your current internet speed to the server closest to you ("nearest server" is not wrong but the other way sounds more eloquent)
(we have almost 50.000 servers worldwide). We test your download (speed with which you receive data from the internet), upload (speed with which you send
data to the internet), connection (maximal number of connections per minute) as well as ping (response time between your computer and the internet).

All tests are performed within your browser over HTTP (TCP) and require no further software other (same issue as with "nearest server")
than a newer browser with activated Flash.

You can test all kind of connections (LTE, UMTS, GPRS, ISDN, DSL, VDSL or cable).
