068 | Internet Link Redundancy (for Web Services and Data Centers)

2025-07-30

We conclude our series on communication link redundancy by exploring perhaps the most critical scenario for modern companies: ensuring continuous Internet access for web services, applications, and data centers. If your website, online store, cloud services, or APIs become unreachable to the outside world, the consequences are immediate — lost customers, lost revenue, and reputational damage.

Providing resilience at this level is complex but absolutely essential, requiring deep understanding of network protocols and architectures.

We’ve already discussed how to ensure reliable connectivity within a single building. Now let’s look at a more complex but equally critical topic: redundancy of communication links between geographically distributed offices or branches. This is crucial for companies where employees across locations need to exchange data, access shared resources (such as a central CRM, file servers, or IP telephony), and work as a unified whole.

In the previous article, we explained why network link redundancy is not just a luxury but a critical need for ensuring business continuity. Today we’ll focus on the most basic — but no less critical — level: communication between servers and network equipment within a single building, whether it’s a server room, data center, or a regular office.

065 | Why Network Resilience Is Not a Luxury, but a Necessity

In today’s world, where every aspect of business depends on IT, and downtime is measured not only in lost revenue but also in missed opportunities and reputational damage, connection stability becomes a critically important factor. From email and internal CRMs to online sales and cloud services — all of it requires constant and reliable network access.

This is where network link redundancy comes into play. It’s not just “insurance” — it’s a fundamental part of your business continuity and high availability strategy for your IT infrastructure.
