Have Fibre with Talktalk - BT says I cannot get fibre?!

Can someone please shed some light?

I'm currently with Talktalk fibre and my DL speed is around 30.
However, when I check what speed I can get with BT via their website, it says up to 12 Mbps, so no fibre!
Same on Plusnet.
Funnily enough even on the TalkTalk website it now says I cannot get fibre (max speed similar to what BT says)... but I do have fibre with them!

On the Vodafone website it says I can get up to 60 and it suggests to get the 68 fibre.
Sky says up to 40.

Can someone explain? I thought that apart from Virgin, they all used the same line?

On the following link it says I can get fibre at my postcode:

There aren't any plans in your area for an infill cabinet at all is there?

When Openreach were in the process of installing the infill cabinet, the databases updated to show us as connected to P7 - although fibre was still being provided by P2.

This meant that the checkers all showed fibre as being unavailable for a few months - despite us using an active FTTC connection.

Sounds like the cab has run out of capacity, and needs something adding - perhaps a new linecard, or a new set of tie cables. Or maybe a new cabinet.

What about this checke?

Does it mention a waiting list?

Thanks I tried entering my phone nr that I have had with TalkTalk for the last 2 years and got the following:

There is no data available for this number. This could be either because it is not a BT line or it is a new BT number that has just been provided. Most new numbers will appear on the checker 24 hours after BT has installed the line.

?!?

I don't know about cabinet installation plans in the area unfortunately...

With a 30 Mbps download unlikely to be affected by an infill cabinet

You need to use the address checker part, since LLU phone numbers are something BT Wholesale have no knowledge about location wise

Hi I have just run the test using my address.
Results look promising.
I posted the screenshot here:

Many thanks for your support.

Your cabinet is at capacity.
If you order elsewhere they need to allocate a new slot to you which doesn't exist. Your existing slot will go to someone else.

Thanks a lot for the explanation.

Does it mean that Vodafone and Sky are lying to me, when they say they can offer me Fibre at a speed of eg 60-70 (Vodafone)? Hence if I switched to Vodafone they would not be able to offer what they promised? Or maybe being a new network they would be able to deal with it differently?

Am I just better off staying with Talktalk then, despite really wanting to switch?

Final question. How frequently does capacity change? Where do I need to check in that graph, to understand when some new capacity is available?
