Trust you,
Your right, I should have said upload rarely slows,
i've only seen it slow twice in over 50 BT speedtests,
the other time it slowed my download speed was 35641,so not worth bothering about.

On WBC the ISP has to pick up their user traffic at 20 nodes scattered around the country, and the node yours goes to depends on your exchange, and in a few cases even the MSAN within the exchange.

That makes calculating the necessary capacity to rent from BT at each node rather difficult for the ISP, so congestion can occur there.

On WBMC normally, (perhaps always), the ISP picks up the traffic at a single node. That is easier for them to manage as they have a reasonable idea of their overall peak demand, but I assume there are other drawbacks.

Which is why I raised the question in my previous post, as I don't know which method Zen use.

There could of course be simple busy-time congestion on the BT side of things at your exchange.

My ISP is BT and I am on the Glasgow Halfway exchange.
I always felt this problem was down to congestion.
But to lose over 90% of my speed with FTTC seems a bit ridiculous.

I was on the phone again last night with BT India.
The "supervisor" was running a line check and apologised for it taking so long because my connection was so slow.
I nearly fell off my chair laughing.

I realise nobody can help with this but at least I get it off my chest.

you are going to get nowhere with BT customer service, you need to email ian livingston, hes very good and always gets back to you, stick to the facts post what you know and I believe something will be done.

Thanks for that, looks as if that's my only option.
Fed up banging my head off the brick wall at the BT end of things.

Hi niknar

I have just seen your post in relation to the speeds that you are receiving with your BT Infinity broadband service, I would like to take a look into this and run some further checks so I can see if there are any issues with the service. If you drop me your details via http://bt.custhelp.com/app/contact_email/c/4950 I will look into this.

Regards David

Why? The OP has not even raised a formal complaint yet. Once that is done and investigated fully is when it should be escalated.

I just do not know why people like you suggest going so far up the chain rather than using processes that are already in place.

And if you believe he actually reads and acts on most of those emails - you are extremely naive.

Sorry, a couple of posts ago I threw a wobbly and decided you were on Zen . 'Doh!

I believe BT Infinity goes via a system no-one else uses, in the same way as their ADSL Max used Central Pluses not the normal Centrals. Can't help otherwise.

I see BT_Care have reappeared, that's good.

Cheers for that.
I'll give BT_Care a go and see if anything comes from that.
I can't understand why it's so difficult to get past BT broadband support and speak to someone higher up the chain.

Because the whole of the "training" and scripted response process is designed to prevent you getting any higher. People who know things are expensive.
