Single links fail. Here is how to design connectivity that keeps working when one path goes down.

Identify what must keep working
List the applications that matter during an outage — safety communications, production reporting, email, payroll — and how much bandwidth each needs. This defines the minimum backup capacity.
Use diverse paths
Resilience comes from diversity. Two terminals from the same provider protect against hardware failure but not a provider outage. Combining satellite with cellular, or two different satellite providers, gives stronger protection.
Automate failover
A multi-WAN firewall detects failure and switches traffic automatically, applying policies so critical traffic gets priority on the backup link.
Monitor both links
A backup link that has silently failed provides no protection. Monitor all links and alert on degradation.
Test
Schedule failover tests and document the results so you know how the site behaves when the primary link drops.
