Update: I have just discovered that performing the test on Google's internet speed test quite often results in 10Mbit/s, but actually performing the test via Ookla on speedtest.net shows the familiar higher bandwidth of around 60Mbit/s or above.
What might be responsible for this huge difference I wonder? Is this evidence of some kind of traffic shaping? Or is there a less sinister possibility?
