[[File:CQM-heavyloss.png|none|frame|Heavy packetloss. Packet loss on an idle line is always bad news...]]
 
[[File:CQM-lowloss.png|none|frame|...even if only 1% (one red dot at the top is 1%). An FTTCA line with 1-3% loss]]
 
If you suspect you have packet loss, also see:
[[File:CQM-speed-change.png|none|frame|line dropped and came back slower and with higher latency]]
 
This FTTC line dropped at 01:50, and came back within a minute or two, however, the speed has dropped (horizontal black line at the top) and also the latency (blue at bottom) has increased. There could be a fault here, but in this case we can clearly see that something has happened. If your line has changed in speed and is shown on the graphs, then diagnostics may find a fault, and the Support Team can help.
