Recently I've been getting periods of a few hours where the router internet is steady orange, i.e. no internet, no loss of sync.
The timing of this one is interesting, just before 8am (BST), possibly suggests an engineer was working on something.
What is the most likely cause of this? FTTC cabinet issue? Sky internal systems issue? I can understand a sync-affecting issue being recurrent, but this is not that.

It doesn’t suggest that at all, in the main, they start at 8am, not before. And quite how an Openreach engineer could conjure a loss of session, but no loss of sync, is beyond me.

I never mentioned Openreach.

You didn’t mention Openreach but did quote FTTC, and do any other network operators use FTTC ?

Last time I saw something like this, it was a contractor doing roadworks, putting a JCB through the fibre cable between the cabinet and the exchange.
The copper lines stayed in sync, but everyone on that cabinet had no onward connectivity until the fibre cable was repaired

I had this happen to my FTTC circuit after the ISP had ruled out my modem / router being the cause they got open reach out He plugged in his tester ( exfo) got a sync like my modem, But couldn't test access to the net on his kit, so he brought a bt router in plugged that in same thing sync not PPPoE session so he went to the cab had to change the port twice to get a working port, sounds like this could be your issue

Could be that or the Port in the cab itself like the fault i experienced took several days to get it fixed due to zen wanting me to test with their loan router modem 1st

I mentioned FTTC since it gave some context to my issue, and I also suggested it could be an internal systems issue within Sky, e.g. Sky engineers or engineers contracted by Sky. The FTTC cab is only part of the journey, and I don't believe my post contradicted this fact.

Interesting, so a fault like this can exist within the cab.

For the record, my reply to Iniltous is equally relevant to your reply.

Yes, but usually affects the whole card or whole cabinet. Changing to a port on another card may restore service .

It could be the ISP that's the problem rather than the cabinet.
I had exactly this same problem with TalkTalk FTTC between February 2020 until July 2022. I suppose first 6 months or so, I didn't experience this. However, after that from time to time every few weeks I had issues where for approximately 10 minutes my internet connection will cease to open any websites. Yet, the router settings will show as connected and Network icon on task bar will show the monitor icon as normal.
Then on its own it will return back to normal. Another occasion like this happened for around 2 hours and it didn't even matter if I rebooted the router. TalkTalk did have too many maintenance's that were causing these outages mostly at night time around 12 to 5am.
However, after switching to BT FTTC in July 2022 I have never ever experienced a single instance of this issue once since being a BT customer! Next month will be exactly 2 years being a BT customer. This shows how much more reliable BT is compared to TalkTalk on the same network and cabinet. For me it was the ISP and not the router as the system uptime did not reset and wasn't related to router firmware update.
You can ask your neighbours to verify if they are experiencing the same problem and whether they are on the same ISP or a different one. That way you can confirm if the problem is with the ISP or your cabinet, internal system or your line.
This sort of experience was very unique for me. I never experienced an issue like this with another ISP where my router connection setting would stay connected but websites would not open. I knew it was TalkTalk being at fault as I was searching downdetector and others were reporting the same issue and the graph chart would reflect the total number of complaints that had the largest spikes of reports.

I'd put this down to a provider issue where the session dropped. Maybe they bounced people from one gateway to another due to maintenance?
Not sure why it would take so long to re-connect.. do you have logs showing tries? I had some issues before with a Cisco 1801 (quite a long time ago) having somr issues with re-connects probably due to config.

Similar, but not identical. It sounds like you maintained an IP address throughout, whereas I did not. Your situation sounds worse than mine!

No, the Sky router just shows lots of unsuccessful attempts to contact the ntp server during the downtime.

This is akin to when a PPP session drops, underlying network tech is online, in your case VDSL. But there is something blocking the communication to the authentication server at the ISP.
So most likely an ISP issue in my opinion but potentially (less likely) a issue on the way there.
Sky have their own links in many exchanges, so could even be that link went down.
Whats interesting is it lasted 4 hours and is a bit late for maintenance hours. So I expect the outage whatever the cause was something failing unexpectedly.

I'm confused because the ptm0 link down in the log does suggest a loss of sync. How do the logs you're getting when this problem occurs compare with what the logs do it you pull the line cable out of the modem?

ptm0 will go down with loss sync, but also when the IP session is lost without losing the sync.
For instance if I drop the session manually via the GUI, which doesn't affect sync, the same message appears:
