        [SM] And rightly so... this put a nice stop to the perverse practice of 
selling contracts stating (up to) 100 Mbps for links that never could reach 
that capacity ever, now an ISP is careful in what they promise... Speedtest 
(especially using the official speedtest app that tries to make users pay 
attention to a number of important points, e.g. not over WiFi, but over an 
ethernet port that has a capacity above the contracted speed) seem to be good 
enough for that purpose. Really over here that is the law and ISP still are 
doing fine and we are taking low single digit thousands of complaints in a 
market with ~40 million households.

        [SM] But one would be wrong, at least the official speedtests over here 
are pretty reliable, but they seem to be competenyly managed. E.g. users need 
to put in the contracted speed (drop down boxes to the select ISP and contract 
name) and the test infrastructure will only start the test if it managed to 
reserver sufficient capacity of the test servers to reliably saturate the 
contracted rate. This is a bit of engineering and not witchcraft, really. ;)

        [SM] If you are talking about speedtests being systemicly wrong in 
getting usabe capacity estimates I disagree, if your point is that a sole focus 
on this measure is missing the way more important point od keeping latency 
under load limited, I fully agree. That point currently is lost on the national 
regulator over here as well.

        [SM] Go team!

        [SM] I admit that I have not looked deeply into these different test 
methods, and will shut up about this topic until I did to avoid wasting your 
time.
