I did a quick check on some of the Streetworks listed nearest to me through ELGIN and highlighted the NGA BT works that I found between Blean and the City centre.
I was a little surprised to get the warning as the last Openreach list had Canterbury knocked back to June 2012. Still, I am in no hurry as I am lucky enough to have 25mb Wireless for the moment.
If you want to keep tabs on works around your nearest BT cabinet, goto the ELGIN site and setup a search (I drew an area round my nearest cab by using the map filter) and you can get a heads up when the cabinets are being installed (that and any other works that happen in the same area).
