lol, getting anything sorted through Openreach is painful... its the reason that I'll be doing my best to avoid them and there infrastructure in future.

Yesterday was just as bad attempting to download a single thread and for the first time in memory even iPlayer ground to a halt several times.

Testing early this morning;

But it soon started to crumble under the strain;

After 15 happy years with ZEN, and only a few months into my VDSL contract, I am reluctantly having to consider the option of installing a second line in order to allow me the soft option of gently leaving ZEN if Andrews and Arnold manage to provide what I personally consider to be the quality of service that I require in the future.

I'm not in a contract anymore, but if I was I'd be pushing hard to be released from it if Zen has no plans to resolve the issue. I'd go as far as taking it to CISAS. I wouldn't want to be forced into paying for a (fairly expensive) service that clearly does not work properly.

Since being moved to another gateway, the issue has improved slightly - no latency/loss problems but daytime speeds (single threaded) are pretty poor and evening speeds just as poor as ever. Overnight both single and multi threaded is flawless. Not what I'd consider a fix and I'm hoping Zen continue investigation.

Are you connected onto Zen's LLU or is the line BT WMBC for backhaul if the later there's a good chance that the problem will follow you if other isp is using BTW

In the time i have been with zen i have experienced issues with throughput and lots of jitter on the tbbqm in the evenings (peak time) on both occasions zen got it sorted both were down to BTW and their Svlan's

Hi all,

Myself and my colleagues in the Core Network team have been working with our Tech Support teams investigating reports of possible congestion for a small number of customers.

So far, we haven't been able to identify a cause in our network, or our links to our suppliers, but we are continuing to investigate this.

It's really important that all issues are reported to our Tech Support teams, and I appreciate that some, if not all of you have raised faults relating to speed issues. For any that haven't, please do, so that we can get the complete picture and identify any commonalities.

If any further clarification is needed, please let me know and I'll see what I can do, however the best path for information is the fault report process with our Tech Support teams.

Hope this helps,

Jon

Here is the issue. Last time this happened a year ago it took Zen nearly three weeks of me pestering them to get moving on the fault. Two of those weeks arguing about sending out an engineer during working hours to report back that no fault was found [i would get charged]. The fault was late evening. Long story short it had taken nearly 3 months of heartache to get a fix.

Not to mention BT categorically denying there was a fault for week on week!

It happened a further 2 times last year without the severity of the earlier fault, the fault being a congested exchange.

I was told yesterday that I would be getting something done on BT side but now BT are coming over and saying that they need a fail on a TAP3.

So I will have to sit for weeks waiting on the line degrading enough to get a move on with BT.
They have a hot Vlan [i think that is right] that my line is connected onto.

It just goes from bad to worse and a quick patch up to silence the moaning.


A bit annoyed to be honest and a fair bit disappointed as I know there is a problem

Any help or ideas from the community would be appreciated

Alas Tavistock is not a Zen POP but TT Wholesale backhaul is an option

Yesterday I searched through my junk box and stuck an old discarded Wi-Fi adaptor on the outside of my study window. At a range of approximately 45 metres the rather weak BT Wi-Fi with Fon guest carrier from my neighbour's Homehub managed to provide the same 8Mbps down with 9Mbps up speeds irrespective of whether it was single or multiple thread from their BT retail 40/10 VDSL. Earlier that afternoon my 80/20 Zen VDSL was only managing a single thread download of 5.7Mbps.
Contacting friends who had Zen 40/10 VDSL via the Penryn exchange in Cornwall revealed that their 40/10 service had a single thread download that was around 30% of their multiple thread download. Another who was served via the Hayle exchange in Cornwall was similarly reduced down to 22%.
I then contacted friends on these two exchanges who were using BT Homehubs and tests revealed practically no degradation between their single and multithread VDSL download speeds.

I'm not a million miles from your friends (or you, I guess, if you're in Devon) and I have similar issues. I have remote access to a BT connection in the next village over (same fibre headend in all likelihood) and it's rock solid.

My connection is slightly "better" at the moment - http://www.thinkbroadband.com/speedtest/results.html... - I love how the x6 graph looks so graceful and flat-out, if only the single thread result was the same

The TAP3 result thing seems to be common practice ,and probably is down to BT rejecting reports on their network being at fault they will see it as more conclusive because it removes most other factors ,but they can give different results , this can because the problem is ISP side, or End users, or sometimes because the TAP3 test node is often on a different part of BT's network But the BT tester is multi threaded and isn't as accurate as other speed testers
