Anglesey has some 18 exchanges, and Menai Bridge is larger with 15 cabinets, 12 with RFS and 10 enabled
Amlwch has 9 cabs, 5 in roll-out and 4 enabled
Holyhead has 19 cabs, and 13 with plans, are any live yet?
The problem with any project over a wide area (32,000 homes approx.) and some 90 potential cabinets, that lots can be going on in other areas but not your own.
The pattern so far looks to be the large exchanges (makes sense as they will host the fibre handover) and cabinets on those, and then creeping out to the smaller exchanges.
