Edge & Connectivity Directory
Edge readiness determines whether a datacenter site can serve latency-sensitive AI inference workloads. GLRI.io's Edge Readiness Index (ERI) scores 40+ metros on IXP proximity, fiber route density, sub-10ms latency reach, and permitting velocity. The gap between a high-ERI and low-ERI site can mean 50-200ms additional latency — dealbreaker for real-time AI applications.

Edge Readiness: Why Latency is the New Land Cost for AI Datacenters
In traditional datacenter选址, power cost and availability were the primary economic drivers. For AI inference workloads, latency has become equally important — and edge readiness determines whether a site can serve real-time applications at all.
The math is compelling: each millisecond of latency adds approximately $0.50 per megabyte of data transfer for inference workloads. For an AI application processing millions of requests daily, the difference between an 8ms edge site (Ashburn) and a 45ms midwest site (Salt Lake City) translates to millions of dollars in operational costs annually.
Ashburn, Virginia remains the definitive edge hub for AI infrastructure, with 12 IXPs, 45 fiber routes, and sub-10ms latency to 70% of the US population. Dallas follows as the primary secondary hub, offering strong connectivity with faster permitting timelines than coastal markets.
