Sorry Max, I honestly thought I was helping but based on below comment you made today I won't say anything more about this.
I am getting sick of tired with some bloke from think broadband forum suggest my full fibre isn't great at all due to BQM spiked and too high latency. But I think it down to TTB server. Not my connection at all.
The speed was fine but getting sick of tired about spiked 160ms on FTTP. I think I have to raised this with Martin, Aquiss to see what he say about this. But, If he says this is normal, then that's is fine by me.
Spikes to 160ms are more worrying without explanation than the small ones *but* it can still be a router issue.. if it's one packet I wouldn't care.. looking at the average going up I suspect it's probably 20% of packets in a 100-second period. It may not kill speed and you may not notice but it depends what you do. If it carries on for days then it may be worth investigating.
Looking at graph which have 'aquiss' in the description in bulk I can't see a pattern that would suggest one big network issue.. some are perfect.. some have some spikes of yellow.. but very few have much blue, which means it's usually one off packets. Yellow spikes are common but they tend to be larger than the ones on your graph which are tiny and regular (ignoring 160ms ones)
For the 160ms ones, it looks a bit like you might be downloading a lot during that time. We don't have that data but if you do it would be interesting to overlay it.
Might be interesting to have an option to add SNMP details where we poll your usage too from router but I worry it would be a niche feature, prone to security risks (technically read only snmp should be ok but with vulnerabilities etc I'd worry about opening that on Internet side). And too many routers/configurations would caude us challenges.
