Diversity in Internet connectivity

Trusted Advisor for IT & Telecommunications Sourcing

Diversity – the underestimated key to grid stability

No company wants to experience an internet outage. But reality shows that a single connection error can paralyze entire business processes.
payment systems come to a standstill, logistics processes stop, ERP systems become inaccessible and operations grind to a halt.

In a nutshell:

Backup lines are only useful if they are truly independent
Many failover connections are based on the same physical infrastructure
Shared PoPs or submarine cables mean that a single fault can affect both connections

The solution:
True reliability is only achieved through diversity, i.e. through multiple, independent network paths that are physically and logically separated.

The following article shows exactly what diversity means and how it protects companies from stagnation.

What does diversity mean for Internet connections?

A backup line is good – but diversity goes one step further.
It means that you secure your connection in different ways, with different technology and/or via other providers.

For example:
If your main connection is via fiber from provider A, your backup can be via a wireless LTE or 5G connection from provider B.
If the fiber cable is damaged, your business stays online thanks to an independent wireless connection on a completely different path.

In short: Diversity not only separates logically, but also physically, thus ensuring real reliability.

Diversity is not just a technical issue; it encompasses several levels on which the reliability of a connection can be increased.

1. diversity of service providers (ISP)

Use different providers for the main and backup lines.
But beware: Some ISPs share the same infrastructure, which means that the desired protection is not available.

2. technological diversity

Use different transmission technologies, e.g:

Glass fiber for primary connection
Copper, LTE or satellite for backup
So you are protected even if one technology fails.

3. diversity on the last mile

Even if the backbone is stable, the “last mile” can become a bottleneck.
Different providers for the last mile ensure additional robustness, even if they use the same path.

4. complete diversity

The highest level of protection
Different providers for:

last mile
IP addresses
Internet gateways
Backbones
Submarine cable

This allows you to achieve maximum redundancy and minimize the risk of simultaneous failure.

Sounds simple? In practice, it’s complex.

Commissioning two providers, combining different technologies – sounds simple.
But in reality, true diversity is a challenge.

The typical stumbling blocks:

Multiple ISPs mean more effort for procurement and administration.
Different technologies require compromises in terms of bandwidth and SLAs.
Regional regulations can restrict new technologies.
A lack of market overview leads to wrong decisions, as many ISPs use the same infrastructure.
