There's a lot of that going on. A lad in work just got it with sky (and is having loads of problems with them not knowing the first thing about anything, and fobbing him off with 17mb and their "algorithms they use to improve linen quality" when he's literally feet from the cabinet) and a woman on my section that lives maybe 50 yards away did a check on her ISP and they said it's not available until march

Really not sure what's going on, but it seems some ISPs are maybe not getting a full list of activated exchanges.

Moving soon, but it will be on the same exchange as I'm on now 40/10. The area I'm moving to hasn't got fibre enabled yet, is there any way to check if it's due guys?

If its in the same exchange area and has no cab, but the rest do its hard to say, you can put your name new phone number in here https://www.btwholesale.com/includes/adsl/main.html or try here http://www.superfast-openreach.co.uk/where-and-when/

Speed may not be 40/10 that's down to distance from cab it could 80/20 (76/19) I imagine though that your area may have had the commercially viable cabs already put in, or the area you are moving to is simply to far out for a fibre cab to be put in because even fibre has a point where its no faster than adsl if the main cab its running from is to far away from the exchange. If its just that BT dont think its worthwhile financially you may get one via the BDUK scheme, although when I could not tell you as I don't know how the scheme runs but details are here. https://www.gov.uk/broadband-delivery-uk

Ermmm... no, not really. The attenuation of fibre optic cables is only around 0.2dB/km. It's purely the length of copper between the customer and the cab that matters, distance to the exchange doesn't.

Thats kind of what I was getting at but explained really badly. If a customers homes is over a certain distance from the pcp, speed improvident would not be worth it over adsl hence BTOr would probably not bother upgrading that cab. I just worded that really badly and used the cab distance from the exchange rather than the distance from the pcp to the homes. Thanks for pointing my mistake and stupid description. Where we live there is one cab about 4 miles (by road the phone cables are more direct I would imagine) from the exchange serving a group of houses, and BT wont lay fibre all that way it seems, there is no current plans to put a fibre cab there, I guess because the outlay vs possible revenue is just not worth it.

I thought that was probably what you meant, but thought it worth mentioning.

Actually I was a bit surprised when I looked it up- I thought they'd got the attenuation well below 0.2dB/km by now, but maybe that's just in the lab and not practicable for real-life fibres.

And when I worked out the numbers it means that of the light put into a 1km fibre, 99.5% of it comes out the other end- which isn't bad going

Not bad going at all and thanks for pointing it out. Shame my Christmas tree fibre optic lights don't know that percentage

Thanks Gary, some useful info there. Don't have a phone number as yet so can only go on the post code

FritzBox · Feb 11, 2014, 11:14:53

Update. Confused. SamKnows Postcode Checker tells me fibre is enabled there, BT's postcode checker says it's not, but then BT's checker tells me I haven't got fibre here either

FritzBox · Feb 14, 2014, 12:08:19

Found this one which tells me I can get fibre at new address
