Hate to say it but I think this has made my mind up to avoid zen for my fttp order next week. I was still considering them even though they were pricier but this GEA migration business seems to be a bit of a potential headache.

Think I’ll give Vodafone a shot
Aquiss or maybe Cuckoo and pay them for the static IP. I find it hard to recommend Zen at present. I’m currently on a gateway with 24ms ping.

To add some postivity to Zen, my FTTP line with them has been in for just over a week now and has been flawless, really pleased with it.

My UDM SE should arrive today, so ill get that swapped over later as I have a script to correct the MTU issues on that.

Latency on its has halfed from my FTTC connection and COD updates now take seconds / minutes rather than hours.

Code:
Pinging 8.8.8.8 with 32 bytes of data:
Reply from 8.8.8.8: bytes=32 time=3ms TTL=116
Reply from 8.8.8.8: bytes=32 time=4ms TTL=116
Reply from 8.8.8.8: bytes=32 time=4ms TTL=116
Reply from 8.8.8.8: bytes=32 time=3ms TTL=116

Ping statistics for 8.8.8.8:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 3ms, Maximum = 4ms, Average = 3ms

Once Lightspeed finish installing ill, compare that against Zen.

TalkTalk are £49 a month for Fibre 900 with a £100 gift card and then add on £112 cashback via Quidco and you are down to £37 ish a month.
That actually sounds pretty good I wonder if it applies for CityFibre packages too. I'm with Vodafone, I don't & have never had any issues with the connection itself as it's FTTP.
It's just the support that is a bit lacking - mainly billing issues when changing contract etc, not sure how much better things are at TalkTalk.

I also wonder how different the latency would be, one of the factors that makes me reluctant to switch now to any other provider.

The problem is, is that it's starting to become pot luck, a bit like Virgin Media.

I agree, the whole selling point of Zen was that the network and the support was solid, if they can't get the network right and the support is lacking, then what exactly are you paying the premium for?

From what I read on the other people which had the issue on the TB forum, I believe they found the issue with some OR equipment. As you have 30 days to correct the issue and then they will release you from the contract, if they are unable to fix it. If they can fix it great, if not you are free to go elsewhere, I am not sure Talk Talk customer service would allow that to be honest.

I have had problems with Zen in the past, with my FTTC connection which I moved to A&A ISP which couldn't correct the issue ether. It turns out after all these years it was the drop wire that needed to be replaced and I only found that out as I've had it moved recently in preparation for FTTP.

A&A ISP are probably the most highly rated for customer service, if you have issues but you do pay for it.

This is my 'pot luck' of hitting a half decent gateway. All my gateways are in London (THN) but there's a big difference between them.

2 weeks ago I was getting <6ms.

@ChrisD. Are you stuck in a contract, and if not will you be leaving then, or you going to wait it out?
I have another ~12 months remaining. Zen have said if they can't fix it in 30 days, they'll release me from it and I'll probably sign up with Aquiss. With that said, I'm waiting on Cuckoo to get back to me.

All they've done so far is awkknowledge that there is an issue and they've said they have set up a smoke ping.

To me, it's a clear issue between OR in the exchange and themselves in London.

Openreach GEA connections are handed off to the ISP within the exchange as a L2 VLAN over a single mode fibre with OR call a Cablelink. Cablelinks are available in 1G and 10G and the ISP can (and usually will) oversubscribe them.

The ISP is responsible for their own backhaul from the exchange to their core POP. This looks like the backhaul is probably contended somewhere along the line. Having had a peek in a couple of exchanges when Zen have had a presence for a while their kit is nothing special and is quite old.

Zen historically resold BT Wholesale connectivity which will be handed over to them via an NNI more than likely in THN. Zen then only need to concern themselves with the transit and peering which is easy in THN as LINX/LONAP and loads of transit providers are in there.

Can someone provide a dictionary?

ISP, VLAN, POP, NNI, THN, LINX, LONAP.

Oh forget it.

I know you said forget it, but if others are interested:

ISP = Internet Service Provider.
VLAN = Virtual LAN.
POP = Point of Presence. A place where ISPs have routers and other equipment.
NNI = Network to Network Interconnect. A logical connection between different networks.
THN = Telehouse North.
LINX = London Internet Exchange. An IXP, Internet Exchange Point.
LONAP = London Access Point. Another IXP.
