As I write this, there are 951 entries on the Speed Wave, with an average download speed of 17.02Mb/s, upload speed of 7.26Mb/s, and ping time of 47ms. Those times are broadly consistent with everyone having a healthy ADSL2 connection, though the upload speeds are rather more generous than you'd expect. Obviously there was a lot of testing going on from workplaces.
That said, if we exclude the top six results (all of which had average speeds over 100Mb/s), the download speed drops to 15.37M/s, while excluding the top six upload results reduces the average upload speed to 6.3Mb/s. I'm still jealous of people with AARnet connections and other high-speed links though.
Thanks everyone for taking part (and if you haven't, the wave is still open).
