Let me get this straight. If BT is throttling my connection, that means that 
they are just randomly but consistently dropping packets instead of letting them 
through?

I assume that normal operation of ICMP would mean that I don't notice this, 
except when ICMP is impaired, this will lead to issues like I'm seeing with the 
online broker app?

I'm quite ready to believe that BT are doing that, although I haven't noticed 
any difference in speed test results. Then again I have heard that BT's 
throttling recognises the speed test sites and doesn't throttle that traffic.

Can I set up probes in smokeping to monitor this?

Thanks
