What's Really in That Private Network Cable?
from My Weird Prompts
When you click "add to private network" in a cloud console, what's actually happening? This episode unpacks the three tiers of cross-data-center connectivity — from hyperscalers with their own submarine cables to mid-tier providers leasing carrier circuits to software-defined overlays running over the public internet. We explore MPLS, VXLAN, dark fiber, and the hard speed-of-light limits that no amount of optimization can beat. Plus: what "private" really means when your traffic leaves the data center.
