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.

4 weeks for BT to ‘install fibre’. They rock up, take a couple of pictures of a tree that’s grown over the pole and say ‘sorry, the council will have to cut the tree’. Amazing.

Obviously frustrating and would've been nice to be highlighted sooner, but how else do you expect them to install your fibre? If your lines are overhead which you are presumably well aware of, an overgrown tree hitting the line is a obviously a big physical obstacle in the way of running a new cable...

They are just telecoms engineers, not tree surgeons lol - it's the council/homeowner's responsibility dependent on where it sits.

You’d think they would have done a survey 4 weeks ago when it was booked in.

Anyway, team 2 arrive. They’re a bit more can do (I believe the first were contractors) and have a lifter, go up the pole that’s in the tree and get the cable over. Fortunately it’s over driveways, so the height can be a tad lower and we’re within the range limit. They’ve actually done a cracking job.

Now we just need team 3, the ‘internal team’.

Interestingly I think they were more bothered by the fact they’d have to change the copper cable to the nearest pole, thereby knocking out several houses internet/phone for a few hours. The furthest pole, that not only being in another tree, but also further away requiring specialist equipment, but at least it had a fibre cable to it.
