The document outlines Neil Shewry's plan to build the Janet Access Infrastructure over 4 years through approximately 20 separate projects. It will replace 1000 customers, 1500 connections, and 300 infrastructure links across 120 points of presence using a common design and delivery approach to avoid having to repeat the process for at least 7-10 years. The process involves designing, buying, building, and transitioning customers to the new infrastructure in a way that minimizes disruption through zero touch provisioning and a target migration window of 30 days. So far, the south and south west regions are currently being built while many other regions are in the design phase, with Scotland to be the next region addressed in 2020.
