Many buildings list two internet providers on a floor plan — but few can survive a real carrier failure. This episode walks property owners, facilities leaders, and IT teams through practical steps to design, validate, and operate carrier diversity that actually reduces outage risk. Alex Morgan interviews Michael Harrington and James Rogers about common misconceptions (separate ISPs isn't enough), physical-path realities in multi-tenant buildings, testing failover, coordinating carrier maintenance, and the operational tradeoffs between cost, uptime, and manageability. Guests share real-world examples of where redundancy failed and what simple, repeatable practices prevented repeat incidents: mapping physical routes, specifying true diverse meet-me rooms, documenting demarc and handoff responsibilities, scheduling staged failover tests, and building runbooks that include carrier contacts and validation checklists. Listeners will walk away with a short checklist and decision points they can apply on the next procurement, retrofit, or outage drill to make carrier diversity a reliable capability rather than a line item on a bid.
