Here in Brasil, the ISP must guarantee packet loss of at most 2% in 90% of measurements. [1] A public comitee manages servers located precisely at exchange points, and, thus at network borders. These servers are used by applications which anybody can run that are used to measure speed from clients to them. Of course, there's always a chance of selective QoS based in packet origin, but this is now illegal (we have a net neutrality law now) and not that hard to investigate if needed. [1] The speed is also rated, but at 30% at any measurement and 70% at long term average.
