In an (admittedly different) enterprise scenario, I see consistent 50-60% peak utilization as right-sized. 75% or more is tagged for an upgrade or at least analysis to understand the traffic patterns. For a big network to deliver 100 Mbps vs. 1 Mbps connectivity to most locations is a very small cost. The big costs are the fixed costs the initial buildout.<p>Marginal capacity changes are pretty cheap. There&#x27;s no technical reason to treat network links as constrained resources. So as a network provider, you only create constraint to make money.<p>Think of it as food &amp; drink in a movie theatre. A bag of popcorn at the Target snack counter is $1.50. A bag of popcorn at the movies is $9. Same product, both high-margin scenarios -- the difference is you&#x27;re captive to the movie theatre.
