psb-bng04 is pretty much useless - each time I'm on it latency is through the roof, packet loss is through the roof.
psb-bng01 and psb-bng03 seem to be OK (apart from these odd huge blips - which I'm convinced is either my router having some sort of fit as the wireless stops working .... or its something at PN's end)

Hi @SteveA,
According to logs your connection is currently routed via psb-bng03. If you see an issue with packet loss again, can you also post WinMTR stats along with the BQM graph please.

Will do - I was hoping to be able to do it for this morning as I left WinMTR running last night but it looks like one of my cats managed to stop it sometime during the night.

SteveA - I've forced myself onto psb-bng04 to see if I get the same, If i don't then it probably rules out the outbound of the BNG (depending how plusnet configure it there may be multiple paths out).
If when you switch BNGs the next is fine the key is to find out what are the common points on the connection you have, e.g. the svlan will be the same for all BNGs so if you are fine on one and new gateway its bad then that pretty much rules out a hot svlan.
As its in the 4-10 zone that would imply some form of congestion (for that time of day) although from some of the graphs its 6am too, which would point less to congestion and more to a faulty link somewhere.
My assumption is there are more paths across BTs network to PLusnet than Plusnet has from the BNG out.
One really good test would be to get rid of your static IP account (not sure how attached you are to your static IP?) and move onto the new network that doesn't go through the BNGs.
Alternatively not sure if plusnet has a second username/password then can give you for say a week to test against to see if you still get lots of packetloss there, might help narrow down which bit of the network is causing your issue and if you can be given a second account that would mean you keep the static IP (that might cause lots of systems issues though so dont hold your breath on being able to get one!)

the way it happens in blocks would suggest some sort of congestion - 4 to 10 during the week you could say was kids coming home from school and then going to bed... but it happens at weekends too, and now there's been these two early morning blocks : way too early to be everyone checking facebook etc before they go to work. I did wonder if its my YouView box doing something funky when its checking for updates but surely it wouldn't take that long.
There's been some low level packet loss this evening... WinMTR shows about 4 lost packets (which is way less that the TBB graphs would suggest) and TS Reader is showing 92 Continuity errors over the same period (from about 18:00)

So different routes there - and you have lower max times through the PN network but I'm not sure how relevant the max times are....

id ignore the max if the average and low are pretty much the same. Also ignore all the middle hops if the end hop is good as they will have lower priority than the destination which is a dedicated ping box. looks like my latency to the BNG is a couple of ms lower but that's about the only latency different, to pingbox you are getting about the same as to the bng like i am.
I'll stay on bng04 as you had problems with that to see if i can get any, my tbb graph is clean at the moment, will see what looks like in the morning too.

no problems overnight - TBB graph shows small blips but WinMTR shows only a 20 packet difference between the first and last hops with averages all between 10 and 18ms.
TSReader (monitoring the multicast TV as i have problems there too ) shows 165 continuity errors in the same period
