Harbour edge refresh without a surprise invoice
A Hong Kong media network planned a 40G upgrade across two PoPs. After Ledger Cohort, the team rebuilt the cost map and found three billed ports with zero traffic for eleven months. They deferred one leg of the upgrade, documented the idle spend, and used the finding template in Network Cost Audit Fundamentals to brief the board. Result: a staged roll-out with a named review date—not an open-ended “trust us” request.
