In business decision-making, survivorship bias is a common pitfall that can lead companies down the wrong path, particularly when it comes to choosing Internet connectivity solutions. Survivorship bias occurs when we focus only on successes, overlooking failures and challenges that don’t make it to the forefront. In the context of Internet connectivity, this bias can mean that businesses put their trust in single-link Direct Internet Access (DIA) connections with seemingly robust SLAs, all while disregarding the hidden risks and failures associated with these traditional solutions.

The reality is that these single-link DIA connections often fail to deliver the resilient, business-grade connectivity companies need. Fortunately, solutions like Fusion’s SD-WAN offer an alternative that bypasses the pitfalls of survivorship bias, providing resilient, cost-effective, and truly business-grade Internet connectivity.

What Is Survivorship Bias?

Survivorship bias happens when decisions are made based on a narrow focus on “successful” outcomes, ignoring the failures or inefficiencies that might reveal a more complete picture. During World War II, for example, engineers analyzed bullet-riddled planes that returned from battle, aiming to reinforce the most-hit areas. However, statistician Abraham Wald realized that focusing only on surviving planes gave a skewed picture. The returning planes were hit in areas that didn’t cause fatal damage, meaning the truly critical areas were those without bullet holes—places that led planes to fail and not return.

In a similar way, survivorship bias in business Internet connectivity leads companies to believe that a single DIA line with a promised SLA will offer reliability. However, this belief overlooks the many cases where single-link DIA lines have failed, leaving companies without access to mission-critical online resources.

The Flawed Promise of Single-Link DIA and SLAs

Single-link DIA solutions, especially those with impressive SLA promises, can create a false sense of security. Businesses may see these solutions as tried and true, yet they ignore the failures of companies that suffered from outages or poor quality with similar setups. The reliability promised by an SLA alone doesn’t account for last-mile issues, physical damage to lines, ISP infrastructure failures, or upstream provider issues— all of which are common in real-world scenarios and don’t fall under SLA guarantees.

Here’s why a single-link DIA is fundamentally flawed:

Single Point of Failure
A single connection, even with a high-quality SLA, is only as strong as the link itself. Any disruption to that link—whether from local issues, maintenance, or natural events—leaves the business entirely offline. An SLA might offer financial compensation, but that’s no substitute for the cost of lost productivity, sales, and client trust.
Misleading SLAs
SLAs on single-link DIA lines promise uptime, but these guarantees rarely cover every possible cause of downtime. Providers may exclude last-mile disruptions, issues caused by third-party providers, or other factors outside their immediate control. In short, SLAs can provide a false sense of reliability.
Overpriced Without Added Resilience
Businesses often believe a single premium DIA connection equates to a “business-grade” experience, but in reality, these links can be overpriced relative to their reliability. The premium cost does not bring additional resilience and often costs more than diversified options.

SD-WAN | A Business-Grade Solution Without the Survivorship Bias

Fusion’s SD-WAN solution breaks free from the limitations of survivorship bias by providing businesses with a truly resilient and reliable Internet connection, without relying on a single point of failure. Here’s how SD-WAN redefines business-grade connectivity:

Multi-Link Resilience
Fusion’s SD-WAN uses multiple links from various providers to create an active-active, high-availability environment. By aggregating multiple connections, Fusion’s SD-WAN automatically detects issues with any one link and reroutes traffic over the others. This configuration eliminates the single point of failure inherent in traditional DIA connections.
Real-Time Performance Monitoring and Traffic Management
Fusion’s SD-WAN constantly monitors each link for latency, jitter, packet loss, and other metrics. When it detects that one link’s performance has degraded, it dynamically shifts traffic to ensure a consistent experience. This real-time traffic management keeps mission-critical applications like VoIP and video conferencing running smoothly, independent of the status of any single link.
Cost-Efficient for True Business-Grade Quality
Unlike premium single-link DIA solutions, Fusion’s SD-WAN doesn’t require the highest-grade, most expensive links to achieve a business-grade experience. By bonding multiple links, Fusion’s solution delivers robust, reliable connectivity at a fraction of the cost of a single high-capacity DIA. Businesses can use a mix of broadband and even LTE or 5G connections to achieve high availability and cost savings.
Advanced SLA Monitoring for Transparency
With traditional DIA solutions, customers must rely on ISP-provided SLA metrics, which can sometimes lack transparency. Fusion’s SD-WAN provides comprehensive visibility into each link’s performance, showing where bottlenecks or failures occur in real-time. This transparency keeps providers accountable and ensures that businesses are aware of their network’s true status, not just what the provider chooses to reveal.

The Benefits of Fusion’s SD-WAN for Overcoming Survivorship Bias in Connectivity

Fusion’s SD-WAN solution allows businesses to overcome survivorship bias by providing a connectivity solution that accounts for real-world challenges rather than relying on the success stories of single-link DIA setups. The benefits are clear:

No More Over-Reliance on “Premium” SLAs
Fusion’s SD-WAN removes the need to rely solely on SLA promises by creating a network that’s inherently more resilient, with redundancy and failover across multiple links. Businesses get the confidence of continuous connectivity without the risk of unexpected outages.
Transparency and Accountability
Fusion’s SD-WAN provides real-time insights into performance metrics, empowering businesses to identify and address connectivity issues as they happen. This visibility eliminates ambiguity, providing data to evaluate each link’s performance and keeping providers honest.
Future-Proof Connectivity at a Lower Cost
By leveraging multiple connections, Fusion’s SD-WAN allows businesses to enjoy resilient, high-performance connectivity that doesn’t require premium DIA costs. The flexibility to use various connection types ensures that businesses can maintain uptime and performance without overpaying for a single, high-capacity line.

Survivorship Bias | The Trap to Avoid in Business Connectivity

While single-link DIA solutions may seem like a safe choice, they leave businesses vulnerable to the pitfalls of survivorship bias. By focusing only on the “successful” connections that haven’t experienced failure yet, businesses can miss the inherent weaknesses in these traditional setups. Fusion’s SD-WAN solution is built on real-world connectivity needs, addressing failures and risks head-on, rather than relying on a single, overpriced link that claims to be bulletproof.

For businesses seeking true business-grade Internet connectivity, Fusion’s SD-WAN is the answer. By providing resilient, cost-effective, and transparent connectivity, Fusion’s SD-WAN ensures businesses can move beyond survivorship bias to build a network that delivers real, reliable performance.
