The chap from BT Openreach thinks the CP's are not updating there data bases quick enough as the are more and more FTTP PON's being lit every day and are ready to order, he says he is seeing it a lot with other cp's.
That's definitely not the reason for Talktalks general unavailability.
If you check any other address on your exchange that has FTTP available you will find they also show unavailable with Talktalk.
Talktalk availability checker updates automatically as each PON shows availability.
If Talktalk are selling FTTP on an exchange, the day it goes live to order it is usually available from Talktalk.
They weren't available on my exchange at all for FTTP.
It was lack of cablelink.
Soon as the cablelink was installed they were available on every FTTP address on the exchange.
As PONs as marked available in my area they are automatically available on the Talktalk FTTP checker.
You posted last week that they told you it WAS lack of a cablelink.
They don't know their ar*e from there elbow.
