Over a week since I booked my fault out and my TBB graphs still looks worse than when I was on FTTC in my old house. Very little in the way of communication by Zen.

In regard to my own connection: at present the browsing has improved but the speeds are still inconsistent between 920 mbps and then down to 200 mbps.

At one time the ZEN systems seemed to be the most robust available with overcapacity being the order of the day and at that time being put onto a ZEN backhaul would have been a bonus but the deterioration seems to have coincided with the ZEN GEA Change.

Since others have indicated that when they were returned to the BTW backhaul it cured the issues I pressed for my own line to be returned to the BTW backhaul and I am waiting to be returned to the BTW backhaul within the next few weeks.

That said, I cannot understand why those who have already been returned to the BTW backhaul are posting about issues if the issues were all cured by a return to the BTW backhaul or do the same or other issues still exist.

I can understand the human desire to know exactly what went wrong and who did it/to find a smoking gun and/or witness the public floggings of offenders but personally I would just like a permanent cure be it from Openreach or from ZEN

Do those who have gone back to a BTW backhaul still have issues?

Hi, I assume you have an open fault with our Technical Support team for this? They should run through all the normal diags before I'm made aware that its related to the issues I'm investigating. Would you be able to sent me a PM with your username so I can confirm that your Exchange/Cablelink is one that I'm aware of?

I will however state that congestion really should not be the cause, we have plenty of capacity in the exchange backhaul, and the core network. Our NOC systems monitor bandwidth usage throughout the network, and we have not seen any traffic drops in the paths for affected users. We have also manually checked the paths and interfaces many times as part of our investigations.

I can only speak for myself....

I suffered 7 weeks of exactly what you seem to be experiencing, very unreliable connectivity and (depending upon router/PPOE) slow speeds or VERY slow speeds. During this time, I asked to be UNmigrated on several occasions, but Zen seemed to regard us as 'free' testers, and persevered with their 'tests' all of which showed the symptom as against the problem (disconnections). At no time did I see inadequate capacity at Zen as connecting via PPPOE using my Mac always gave a solid full bandwidth. Eventually, after running iPerf and studying the results here with a friend, and presenting the findings, Zen did instigate my migration back to BTW (I am not saying that was the ultimate trigger, pretty much everything else had been tried, and high level conferences with BTW specialists whilst Zen engineer was here may also have been the deciding factor). I post about the issues to try to assist people with the same problems, isn't that the purpose of Forums? Anyway, as I said, speaking for myself, the issue is solved, but I am the only one that I know for sure was UNmigrated, however I am happy to be corrected, and honestly, I suspect that It's really because I made such a stink about this. I WOULD like to know the real reasons behind this, for my own satisfaction, but I really can't say that I have seen one yet, only 'fixes'. I am not interested in floggings, only to understand, but if you want a cure, either get UNmigrated, or have a second line put in on BTW, and hope that the GEA migrated line fixes itself.

Bravo Brandon.

This is a very naive comment, would you rather we leave you too it?

No. - Of course not.

I am sorry if I phrased that badly as I did not want to give offence.

It just that the thread is enormous and it is hard to keep track is where we are up to.

We know that some have returned to a BTW backhaul and that seemed to have created a cure for them but next the same posters seem to refer to an ongoing problem which indicates that there is still an issue for them.

ZEN have arrange to put my line back onto a BTW backhaul but it will take a few weeks and my concern is that if other who have already been returned to the BTW backhaul are still experiencing similar problems as before then perhaps I should be looking to move to BT or or Talktalk.

No No ! - NOT 'people' (as far as I am aware, and nobody has disputed that so far). As I stated, there only seems to be ONE person migrated back, and that is me.

There IS an ongoing problem, just because I don't have it doesn't make it go away! I am simply trying to support people going through the 7 weeks of problems I had to deal with (12 weeks in the case of FakeJake)

And I REPEAT, going back to BTW has solved 'MY' issue - as it stands, we do NOT know for certain it will fix anyone else's. However, your experience, and sharing it with others may very well help in understanding this problem.

I would go one step further and say being unmigrated hasn't solved the problem, its purely a work around while Zen investigate/resolve the issue. Its like a garage loaning you a car while they repair yours or taking a detour because the motorway is blocked, this issue still needs fixing by Zen (or Openreach).

Fair point Dect. As I said earlier, when there is a proper fix, I hope we're informed, and can then make a reasoned decision if we want to try again.

I am intrigued that there do seem to be a few more people coming out of the woodwork, but it's hard to be sure it's the same issue as there are so many variables, which is where we can help, but of course it doesn't help when people are convinced its Zen's bandwidth, or some obscure routing issue, both of which theories 'seem' to be debunked already (although, never say never), and extra information may change where the finger points.
