During the three months when my 80-20 VDSL was regularly reduced during the working day and evening to this typical example;

Whilst when the peak was over it always provided full speed overnight;

Zen refused my request to leave without paying an exit fee.

Eventually Zen upgraded their London Hub and my single thread degradation during busy periods disappeared.

Alas I notice that this type of peak time performance degradation is slowly returning;

But, I am now relieved to say that my initial 12 month VDSL contract period will end tomorrow.

Fixed.

So they put me on a new VLAN (I think thats what they said they were doing, I was at work and doing several things at once when they called) Apparently the one I was on was congested.


The result:

Looks like a definite improvement. I hope the fix works long term for you.

I've been shuffled onto different SVLANs several times in an effort to avoid congestion and the problems for me always return. I'm on BT Wholesale back-haul and my particular problem has been blamed on BT Wholesale continually overloading their SVLANs. Its been a never ending battle to maintain a decent connection, a huge waste of time and effort.

Sounds bad dude. Hopfully it doesn't degrade again, if it does I'll be back on to them.

Mine is still not fixed yet, this was a early morning test when things are quiter , looks like it's congestion because it's nowhere near during the day time or evenings even after 12am , this result isnt quite perfect on the single thread , but nearly maxing

That looks somewhat better than mine, I have about 50Mbps single thread vs 73Mbps for 6 threads. At one point the single thread number was 20Mbps so it's been improved.

I don't know how much Zen can do, my line is on GEA whereas it was originally on BT WBC backhaul.

To me this is congestion or a contention issue, perhaps if they didn't route so much via their London data centre and used their Manchester one instead this wouldn't be happening? What is even more disappointingly is that unlike most if not all isp's Zen are unique in that they have peering and other data transit connectivity in or near Manchester but choose not to use it and overload other parts of their network doing this doesn't make any sense to me
