Last-Mile Diversity
A second independent last-mile path from a different carrier on a physically separate route, eliminating the single failure domain. Automatically fails over under SD-WAN steering so a fibre cut or cabinet outage never takes the site down.
Overview
A single fibre entering your building is a single point of failure — a backhoe in the wrong place, a flooded manhole, or an accidental cut during roadwork takes your entire business offline until it is repaired. Last-Mile Diversity ensures no single physical path carries all your traffic. We provision two or more physically diverse last-mile connections — different fibre routes, different cable ducts, different exchange points — so that a cut on any one path leaves your business connected through the remaining route.
Clevertek scopes every engagement to your environment — capacity, sites, compliance and support model — so you get a tailored plan rather than a fixed SKU. Pricing is quote-only, and our solutions architects will work through your requirements before any proposal.
Our approach
We audit your current last-mile infrastructure to identify single points of failure in the physical path from your site to the nearest network aggregation point. We then design and provision a diverse second path — using a different carrier, a different cable route, a different technology (fibre vs fixed wireless), and physically separated entry points into your building. Both paths are monitored and load-balanced in normal operation, with automatic failover when the primary path degrades or drops.
Why work with us
True physical diversity
Different cable ducts, different carrier fibre, different building entry points — not just a diverse logical path on the same physical infrastructure.
Multi-technology diversity
Primary fibre plus secondary fixed wireless, LTE/5G, or satellite — different physical failure modes cannot break both paths simultaneously.
Path monitoring and failover
Both paths are continuously monitored for latency, throughput, and availability. Automatic failover activates the secondary path within seconds.
Site audit before design
Physical survey of your site to document cable entry points, duct availability, and carrier access in the area — design is data-driven, not assumed.
Coordination with carriers
We handle carrier engagement for diverse route provisioning, trenching coordination, and cross-connect ordering — your team manages none of it.
Load-balanced in normal operation
Diverse paths carry traffic in normal operation, not as cold standby — you get full use of both circuits while maintaining failover capacity.
Key benefits
What this solution delivers for your business.
Protection against physical fibre cuts
The most common cause of business internet outages is accidental fibre damage during construction. Diverse physical paths eliminate this single point of failure.
Near-zero downtime from last-mile incidents
A backhoe cut, flood, or fire that destroys one path leaves the other intact — traffic shifts within seconds.
Carrier-independent resilience
Diverse paths from different carriers mean a carrier network fault, power outage at their exchange, or routing error affects at most one of your paths.
Reducing rebuild time from weeks to zero
A single-path fibre cut can take 3-7 days to repair. With diverse paths, the cut is repaired without urgency — your business stays connected throughout.
Compliance with resilience mandates
BFSI, healthcare, and regulated industries increasingly require physical diversity in network infrastructure. Documented diverse paths satisfy audit requirements.
Combined bandwidth during normal operation
Both paths carry production traffic — you get the combined bandwidth of both circuits, not just a cold standby that consumes budget without delivering throughput.

Where it helps
Real-world scenarios where this solution delivers measurable outcomes.
Mission-critical single site
A corporate headquarters or data centre where a single fibre cut would halt all business operations — provision a diverse second path on a different carrier and different route.
Financial services compliance
RBI and SEBI guidelines increasingly mandate physical diversity for financial infrastructure. Documented diverse last-mile paths satisfy audit requirements.
Healthcare facility
Hospitals and diagnostic centres that depend on cloud-based health records, telemedicine, and real-time monitoring — zero tolerance for last-mile outages.
Manufacturing with cloud-dependent operations
Factories running cloud-based ERP, inventory systems, and quality management — a last-mile outage halts production lines, not just email.
Questions buyers actually ask
Does diverse mean completely different infrastructure?
Yes — different cable ducts, different carrier fibres, and different building entry points. We document the physical path of each connection to verify diversity.
What if fibre diversity is not available at my location?
We use alternative technologies for the secondary path — fixed wireless, LTE/5G, or satellite — providing technology diversity that has different failure modes from fibre.
How much more does diverse last mile cost?
The secondary circuit adds its own monthly cost. However, the combined capacity is usable during normal operation, so you get productive bandwidth for the investment rather than paying for a pure standby.
Does this work with my current DIA setup?
Yes. We build the diverse path alongside your existing DIA circuit. Both can be bonded through the carrier aggregation appliance for combined throughput.
