Path resilience
Redundant uplinks, WAN diversity, routing behavior, and alternate traffic paths.
Resilience review
Failure is inevitable. Business interruption does not have to be.
A resilience review focuses on whether your infrastructure can keep operating, fail over predictably, and recover quickly when a component, path, provider, or system fails. Custom-scoped application resiliency and disaster recovery planning can extend this work to service dependencies, recovery assumptions, and failover validation.
What resilience means
Resilience is engineered tolerance for failure.
Resilience: the ability of an IT environment to keep operating, recover quickly, and limit business impact when something fails.
The goal is not to pretend failure can be eliminated. The goal is to prevent one failed device, circuit, power source, or dependency from becoming an uncontrolled outage.
Device resilience
HA pairs, redundant core services, gateway availability, and clustered infrastructure.
Operational resilience
Monitoring, ownership, configuration backups, recovery procedures, and change readiness.
Dependency resilience
Power, DNS, authentication, upstream providers, and other services that can create hidden failure domains.
Questions the review answers
Do you know what happens when something actually fails?
What can fail?
Identify concentrated dependencies and single points of failure across the environment.
What takes over?
Evaluate whether backup devices, circuits, and paths are intentionally designed and documented.
What is the blast radius?
Translate technical failure into the users, applications, sites, and business functions that could be affected.
Typical review areas
Resilience is more than a second circuit.
