OK, I'm not as patient as I'd like to think.
I finally gave in and sent the question to [email protected]
and got the following very helpful reply.
Thank you for your interest in fibre broadband.
The cab that serves your premises, cab 61, is scheduled for deployment in January 2013,the cabinet in question is current planned as FTTC.
There is ongoing work requiring traffic management which has a completion date of November.
Please be aware that the engineering required to commission a Fibre Broadband cabinet is often complex and should conditions on the ground change, there is a small risk that the delivery date may be effected. Please track the date for commissioning through the line checker of your chosen service provider.
OK, it's a bit disappointing, but at least I can stop checking availability on a daily basis.
So, roll on January . . . . or Feb, or Mar . . . Ooo. Just in time for fibre on demand!
