I contacted bt to see about infinity they say yes sir it should be available between now in may does this mean it will end up may 2015 or are we getting close to going live i spoke to bt engineer and he said all the cabinets have power to them now
If you use this checker it will tell what cabinet you are on and what services it can receive
You can then email Openreach on firstname.lastname@example.org giving them your cabinet number, exchange telephone number and address and they should be able to reply with the up to date information. They can take a coupe of weeks to reply.
Talktalk may be accepting orders but not giving an installation date until later. There really is nothing you can do except wait for BT to accept your order.
