My line has been fairly solid since BTO came out a couple of months ago and fixed something at the cabinet and replaced the copper pair from the outside of my house to the master socket, but for the last month or so (which ties in with being migrated to the 52/10 product from the old 40/20 product) my line is clearing down at least twice a day (four times today according to my Fritz!Box).
I've raised a call with support but got to the usual "if it's your equipment we'll charge you" bit and just wondered whether I could garner any additional support here before I take the plunge.
The confusing thing is, the disconnections (a sample of the logs shown below for reference) seem to occur around the same time each day, normally between 8-9 am and 8-9pm with a couple in the early hours.
So the important parts; nothing in my house has changed between going from stable/happy line to one that is less so. The Fritz!Box has not been changed, no firmware updates etc. Nada!
I haven't got round to switching back to the Plusnet router (in fact, in the 18+ months I've been with Plusnet, I've NEVER used their router outside of debugging issues so I can't see it making a difference, I'd expect a line that's been working for 18+ months with my Fritz!Box to continue doing so unless there is another issue at the cabinet or somewhere along the way).
The previous issue which BTO dealt with was the cab losing sync with the exchange - now as unlikely as it might be for the same issue to occur, the fact that my logs are telling me that I've lost synchronisation is ringing alarm bells.
Are there any additional line checks or more deeper checks that can be done that a "normal" CSA wouldn't have done already? My logs give you a good insight into how often this is happening and I wonder if you can tally them up to events at your end - for instance, can you tell what caused the loss of sync (i.e. the modem dropping the connection at my end or the exchange/cabinet end?)

It may not help you much, but I'm also on a 55/10-provisioned line and I haven't seen any change in the amount of disconnects I've had. I normally have either zero DSL disconnects in a week or just one. The most common time for a disconnect to happen is around 7am, and the connection is usually back up within a minute.
I've got a BT ECI modem and a now ancient, but still adequate, Netgear WNR1000v3 router (2011 vintage, with a few firmware upgrades). Last time I checked, my BT IP profile when I was on 80/20 (which I was for a couple of weeks after moving to the new network, before being throttled back to 40/20) was around 64mbps downstream,
There have been a couple of times when I was getting lots of disconnects, but each time these were traced to Openreach problems.

I've switched to using the Plusnet Hub One in the master socket with a micro filter and will continue to monitor over the weekend, if I've had anywhere near the number of disconnects I've had over the past couple of days I will be insisting on an engineer as I think I've done everything reasonably possible to triage it at my end.

Sadly, I suspect you'll have to phone up and start a fault report.
If you're really lucky, someone from Plusnet might generate a connection graph and post it here, but that doesn't happen as often as it used to.

The Openreach engineer has just left having been able to find no faults on the line. He confirmed that my internal wiring was likely not at fault and confirmed that having gone through 3 modems (The Fritz!Box, The Plusnet One Hub and now a BT Openreach modem and all exhibit the same issues, I've done everything I can to rule out an issue in my property.
He agreed that it was more than a coincidence that the line had become less stable since the re-grade to 55/10 but I think he was clutching at straws having not found anything on the line.
He referred me back to Plusnet to discuss next steps but I'm genuinely at a loss as to what to do next - 3 disconnections per day cannot be seen as providing a reliable service in anyone's books, certainly not when we/I rely more and more on our connections for our every day lives.
I've updated the service call on the Plusnet site and eagerly await their response but wondered if anybody here had any ideas.

That's fair enough, I'll await the faults team reviewing the case. I was surprised there was no need to check the cabinet/exchange but perhaps if the line is in sync at the time of visit and there are no CRC errors on the line then that's not necessary (I would have thought that if the customer has proof - which aligns with your graph above) that there are frequent disconnects that they'd investigate further from the property seeing as he was pretty certain it was nothing on my side causing the issue.
