You can take a look at your graph and compare it to the examples below to see if there is a match.
{{CPbox|#Click on the line you want to view
#Clicking on the graph again will show a 7 day's worth of graphs with options there to view 30 and 60 days}}
=Examples=
Below are a few examples of slow lines and their graphs.
==Lots of traffic on the line==
[[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%).
If you suspect you have packet loss, also see:
*[[Packet Loss]] - a page with more (slightly technical) details about packet loss
*[[CQM Graphs#

==Line dropped and speed changed==
[[File:CQM-speed-change.png|none|frame|line dropped and came back slower and with higher latency]]
This 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.
