Ok so the middle one I presume matches the left of your BQM.. it shows the same latency spike.
We show 170ms scale CQM is 600ms - but the patterm for 2pm-6pm is the same on there.
If you look at that period the AAISP CQM shows the bandwidth usage (dark green) was also high).. so it confirms that's usage based saturation probably.. looks likw you have an FTTC 80Mbps product probably? (or 100Mbps FTTH or something).
To be honest, I'd ask the guys on #a&a IRC channel about it.. they will probably be able to say it needs looking into or not... or if you don't use th at ask AAISP support.. not in the "this ia bad" way just ask about the fact you're seeing the graph veing much more variable to others. They have access to a lot more data about your line (support) so they may have ideas.
