Speed tester

[#1]

A long time ago, (like years), PN suggested that the speed tester at http://www.mybroadbandspeed.co.uk/ shouldn't be used. I see that the warning about inaccurate speed indication is still there, but having given it a run several times over the past couple of weeks it seems pretty accurate to me.
Is there still "officially" a problem with using it?

I always use the BTW test - http://www.speedtest.btwholesale.com/

Hi nozzer
We always recommend using http://speedtest.btwholesale.com/, the reason for this being is that you can send the results to us if you are having problems and they can be used in the diagnosis of faults.
