TiPS Episode 26 0216 - The MYTH of Five Nines in Your NG911 ESInet

Source: https://www.podbean.com/eau/pb-3tsyf-... In this episode of TiPS: Today in Public Safety, Fletch takes a hard look at one of the most overused comfort blankets in network design: “five nines.” It sounds impressive on a slide deck. It sounds responsible in a contract. It even looks reassuring when someone puts it in a glossy brochure. But in a real ESInet, “99.999%” is often just a number that describes one component, in one place, under one set of assumptions. And the public does not call 9-1-1 to test your component availability. They call because their worst day just started, and they need an end-to-end system that actually works. This episode breaks down what “five nines” really means, why it gets misused, and how reliability claims can fall apart the moment you zoom out and look at the full path: origination network, call routing, NG911 core services, GIS dependencies, redundancy design, PSAP operations, and the handoffs between all of it. You will also hear why “sunny day outages” happen so often, and why partial failures and intermittent issues can be more dangerous than a total outage, because they hide in the cracks and quietly break workflows. If you are responsible for NG911 planning, ESInet procurement, governance, cybersecurity, operations, or vendor oversight, this is the episode that helps you stop buying numbers and start buying outcomes. Because the mission is not five nines. The mission is: the call and the data get through. Every time. In this episode, we cover: What “five nines” actually means in real downtime Why component SLAs do not equal mission success The end-to-end reality of ESInet dependencies Hidden single points of failure you forgot you had What to measure instead: outcomes, failover behavior, and operational continuity The questions every PSAP, 911 authority, and state program should be asking TiPS: Today in Public Safety is where we talk real-world 9-1-1, real-world NG911, and we translate buzzwords into operational reality.   Follow Fletch for more: x.com/@Fletch911 Fletch.TV 911TiPS.com   Copyright ©2026 Fletch911, LLC Media Productions http://Fletch911.com
