Reliable info for fibre and other exchange changes

[#1]

OK please shout if I have missed this info but i have searched and searched the internet and no where can I find a reliable source of info for what is happening to my local exchange with regard to increasing the speeds (21cn etc) or installing fibre and when it will happen.
Now I am sure I am not alone in this and for anyone thinking of moving house this must be a real consideration these days so please does anyone have any good sources or could perhaps PlusNet create their own and be a market leader in telling the customers what they want (or don't want   ) to hear.
cheers

Try this mate look for fttc date

Thanks but I have already tried that site but the dates are just random when ever they do display them.  The 21CN info for example keeps changing almost weekly.  One minute its happening within weeks, then there is no date then it is months away and so it goes on

Hi,
I'll be updating this list this week, the latest data came out a couple of days ago:
http://community.plus.net/21cn-exchange-availability/
Note, for fibre, even if the exchange shows as enabled you may not yet be able to get it, checking your phone number here will give you the most accurate information for your line:
