This may not be directly relevant because I'm with IDNet (eta- 80/20 FTTC) on Zen backhaul, but I'm recently seeing similar (the timings are different):

My Broadband Ping

The second red spike is me rebooting the router; I don't know if it's possible to check backhaul routing. I'm in South Oxfordshire.

This has only started happening in the last month or so, prior to that I seemed to be immune to all this re-routing malarky

I'm in the North (far closer to Manchester than London) and got bounced to a London router at about 3am, having been solidly connected to Manchester without a break since early August. I only noticed when I was doing some traceroutes to diagnose an unrelated problem.

I don't think my internet has actually experienced an outage (unless it was at 3am while I was fast asleep!), but it was very slow when reconnecting - I normally click Reconnect in the FritzBox interface a few times until I get a MAN gateway, normally it takes a few seconds but it was taking up to a minute for some reason.

With IDNet you don't get to see the routing due to the way it goes over Zen's backhaul, but you can safely assume that higher ping is because you are going up to Manchester then back down to IDNets gateways in London.

It's why I left them, they say they are the lowest latency network in the UK, then give you that nonsense of Zen's backhaul.

If I did anything that was latency-sensitive I might do the same, but as it is it's only a minor occasional irritation. On the whole I'm very happy with IDNet, have been for years.

I'll say one thing though- I keep an eye on a few other ISPs in case I ever feel the need to migrate, there's one less name on the list than there used to be.

Same here - I was on Manchester but live in London, bounced my connection to get a London one, which I did. But I had no internet for several minutes (normally takes a couple of seconds).

about 2 am - my latency went up to 20ms (from about 5) - tracert shows a couple of wh-man & then a couple of thn-lon so I guess being routed vi Manchester - but at least no signs of dropped packets

Hmmm. I had an outage, and when it came back my latency had tripled.
Tried reconnecting a couple of times but took ages to reconnect.

See my BQM

Now I see on my portal:
Zen Fibre GEA Migration Fulfilled on 19/10/2022

So is that me with high pings forever then?

My PoP was acc-aln2.l-bec (Beckenham in SE London where I live)
Now it's BNG4.WH-MAN-RE0 (Manchester?)

I an fed up with Zen's network rearrangement, I suspect it is to save money and instigated by bean counters.
I am off to A&A in November so wont have to put up with this [censored] anymore.

there was nothing wrong with TT wholesales network which they used to use,
