Recently I moved from Vodafone FTTP (OR) to YouFibre 1gb package.
It was cheaper than Vodafone and they'd pay my termination fee - was a no brainer really.

However, slightly regretting it.
Found out they use CGNAT and all that jazz, but I have been experiencing service drop outs frequently.

I am using a Firewalla Purple as my router. The router OS monitors the connectivity to the ISP and today I've experienced this many drop outs.

I've disabled IPv6 completely and using just the CGNAT address for outbound connectivity.
Wondered if anyone else has experienced issues like this? or could it be a common CGNAT type issue? Either way, it has caused VPN connectivity drops.

I've raised the issue with YouFibre, but awaiting a response. Perhaps a static IPv4 address might help?
 
Does the ISP provide a router that could be tested?

You could put your personal router downstream of the ISP router to monitor external connectivity (not just that the ISP router maintains its LAN/internal connection).
 
I have a static IP (therefore not behind CGNAT) and haven’t had any connection drops. In fact I’ve got some TCP sessions that have been up for nearly 3 weeks now uninterrupted. Might be a CGNAT thing.

I've had YouFibre since June last year and the only time I've had any downtime was when we switched from the gigabit plan to the 8Gbps plan and the ONT **** the bed. But like the other Nate, I've got a static IP as well. For the £5 a month they charge non-business plans, it's a no-brainer.
 
How. What mechanism? What's it targeting?
It performs ping tests against:
1.1.1.1
8.8.8.8
9.9.9.9

It then performs a DNS test against github.com

Complaints team are working with me to try and resolve. They've given me a static IP and i've setup a ThinkBroadband monitor to document it.
Funnily enough, from Saturday evening through to Monday morning I didn't have any disconnections what so ever. Then it's all started again. Not as bad as Friday might I add.

IPv6 is completely off as well now.
In the grand scheme of things, the downtime realistically is about 10-30 seconds. My Home Hub display doesn't even recognise a disconnect because of how short it is, but my wife's VPN does and will need re-establishing.

Weird one now.
I use NextDNS as my DNS resolver (as it has cyber security features etc), however I recall changing it from 1.1.1.1 & 8.8.8.8 to NextDNS's servers and gradually started having issues.
Swapped this back (to 1.1.1.1 and 8.8.8.8) at around 11:30 and stopped receiving packet loss.
Weird thing is, the Firewalla tests by pinging an IP, which shouldn't need DNS.
Note that I have my ThinkBroadband monitor setup to ping my gateway and it also experiences packet loss during the times that my Firewalla reports issues.

YouFibre are coming out on Saturday to swap my ONT though. So i'll monitor the service for the next couple of days.
 
Few days on going and still have my DNS set to 1.1.1.1 and 8.8.8.8. Connection has been fine.
ONT swap tomorrow, so will monitor with current DNS for 3-4 hours then swap to NextDNS and see what happens.

And what is it determining as the criteria for being disconnected? EG x number of no responses and a certain number of responses after the fact to consider it restored. Is it all three or any of the three? A 2 to 3 minute outage seems somewhat significant, but not convinced that it is true. Given the times indicated, are you actively doing anything around those times and notice an actual disconnect/outage?

What about targeting your next hop instead?

Given that it is ICMP, that may play into the somewhat unreliability that ICMP is.
