BT Wholesale Checker had made change again. Reduced on both download & upload speed from this morning.

Anyone else had noticed it? The left side is old one, the right side is made change today (new one)

Ever heard of feedback loops and using data from an actual service to feed back into what was previously estimated data?

BTw should get it right, not mess us around. My mate had complaint that his speed estimated had changed from 78/19 to 67/16. And it now that ISP will tell him u only getting 67/16 not 78/19 when first sign up.

Crafty BTw again. How many more are BTw going to reduced again in future?

In reply to a post by MrSaffron:

Certainly looks that way. The 'clean' estimate now accurately reflects the cross-talk ravaged state of this area due to the very high uptake smile

In my own case high dropped from 80 to 74.5, low from 66 to 56, with upstream from 20-20 to 20-17.4.

Impacted shows way more extreme drops in percentage terms.

EDIT: The maximum is actually pretty much spot on too.

Line 1: Attainable rate (kbit/s) 74204
Line 2: Attainable rate (kbit/s) 71320

And how do you get it right, when cross talk can vary over time and depends on the level of take-up in the future.

To be honest and perfectly frank, if I was on a ISP help desk and someone complained that the estimate had changed, then I'd be pointing them at the dictionary explanation of what an estimate is. It is not a 100% guaranteed figure. The key thing is what speeds you actually get from the live connection.

After all your years surely you have learnt that xDSL technology includes uncertainties in terms of the speed you will get, particularly as so many outside influences can impact on the speeds.

Even if you had FTTH installed, the connection speed might be constant (assuming no faults in the fibre) but the throughput would still be impacted.

Very interesting!! My adsl2+ estimate on the BTW site has plummetted since the service went live back in December.
Now showing up to 13Mb -with a range of 7.5 to 17 -formerly was showing 17Mb with a range of 13-20 !!!!!
I'm actually getting ~ 16Mb d/load speeds on a synch of 18.8Mb - but its noticeable that even tho' the line appears quite stable, the synch speed has dropped on every (rare) disconnection; since December -I've "lost" about 1Mb downstream.

Yeah very true. When I signed up it was estimated 79.9 down and 20.0 up but in real term on my speed throughput is only getting 72 down and 17 up (I expecting it will reduced to around 62 down and 12 up when the cabinet get fiill up later and crosstalk)

We have to wait for BT to roll out vectoring to solve this speed reduced.
