I would not be expecting commercial roll-out. That is due to complete end of Spring 2014 so if no RFS date yet then unlikely to be happening.
I think this is cabinet 4 (cannot see number in photo)
i.e. around SL3 6JB
No mention of the exchange on
The target for Bucks and Herts is actually fairly low 90% connected to fibre based (note not superfast) so while not the most rural area there is a risk of being overlooked as other more rural areas may have made a larger noise to get improvements. i.e. time to chance council for information
Six cabinets on the exchange probably 1000 premises and if all cabs were enabled ~ 70% would get superfast speeds, another good 10% getting 15 to 24 Mbps. Two cabinets look very small and unlikely to be enabled even via a BDUK project. The other four are roughly equal in size.
