Resilient connectivity requires more than two circuits. Organizations need to validate carriers, physical entrances, conduit paths, upstream dependencies, service levels, failover design, and contract terms against business requirements.
Questions to answer before deciding
Do primary and backup circuits share a carrier or physical path?
Which applications require deterministic performance?
Are renewal deadlines and price escalators documented?
Does the failover design get tested under realistic conditions?

SD-WAN vs. Dedicated Fiber: How to Choose for Enterprise Connectivity
SD-WAN and dedicated fiber solve different problems. Understanding which architecture fits your traffic profile is the difference between a resilient network and an expensive one.
Not by itself. SD-WAN manages traffic across available links. Dedicated fiber provides a transport option. Many designs use both.
What is true carrier diversity?
True diversity reduces shared failure points across carriers, building entrances, conduit routes, meet-me rooms, and upstream networks.
When should telecom contracts be reviewed?
Begin before the notice deadline leaves the organization without leverage. A review should cover usage, pricing, SLAs, redundancy, installation terms, and exit rights.
Need an independent infrastructure review?
Start with your requirements, current environment, commercial terms, and decision timeline.
