Approximately hourly latency spikes
What it sounds like. Approximately every hour I have a very noticeable latency spike, which can last a couple seconds or be up to around 5 or more minutes. If my memory serves, this has only started happening relatively recently, in the past 3-5 weeks. I have experienced this wired and over wifi, and have had it happen at different times of day while I've been doing different things. It is (unsurprisingly) most noticeable when gaming, as latency spikes of 400, 600, 800 or more are impossible to miss, but it is also impacting me when I'm trying to work, as git and github dont like 4s latencies either -most stuff loads forever or just gives up when it happens.
I had the hub 3 in modem mode, as I'm using my own (mesh) access points, as the vm kit simply cant cover my home, so I switched the hub to router mode in case it was a firmware bug (double NAT-ing myself - nice) but it has not helped.
This is not relevant to network load, these are consistent spikes that happen daily, and I have no reason to believe it's "bufferbloat" or whatever. I have had bqm set up from the 30th of March, when I switched the hub to router mode, to see what latency looks like from the outside, and it's clearly there. I also have an example from the 4-5th of April which show what the latency looks like under consistent load (during a backup upload) - higher base/average but the high spikes are still there. BQM only seems to show up to 160ms, but I have experienced far FAR higher spikes.
I have pinhole reset my hub 3 (~2am apr 7), but i doubt it will help.
apr 1
apr 2 (red bar is unrelated, breakers tripped)
apr 3
apr 5 (~4pm backup upload finishes)
apr 6

The vm engineer that visited couldnt find anything obviously wrong with the hub, but they offered to replace my hub 3 with a hub 5, and it seems to have fixed it. My latency is now nice and consistent, thanks.
