Diversity, the underestimated key to network stability<\/h2>\n<\/div>\n<\/div>\n\n\n\n

\n
\n
No company wants to experience an internet outage. But reality shows that a single connection error can paralyze entire business processes.<\/strong>
payment systems come to a standstill, logistics processes stop, ERP systems become inaccessible and operations grind to a halt. <\/p>\n\n\n\n
<\/div>\n\n\n\n
In a nutshell:<\/strong><\/p>\n\n\n\n
\n
Backup lines are only useful if they are truly independent<\/li>\n\n\n\n
Many failover connections are based on the same physical infrastructure<\/li>\n\n\n\n
Shared PoPs or submarine cables mean that a single fault can affect both connections<\/li>\n<\/ul>\n\n\n\n
<\/div>\n\n\n\n
The solution:<\/strong>
True reliability is only achieved through diversity<\/strong>, i.e. through multiple, independent network paths<\/a> that are physically and logically separated.<\/p>\n\n\n\n
<\/div>\n\n\n\n
The following article shows exactly what diversity means and how it protects companies from stagnation.<\/p>\n\n\n\n

What does diversity mean for internet connections?<\/h3>\n\n\n\n
\n
\n
A backup line is good, but diversity goes one step further.<\/strong>
It means that you secure your connection in different ways, with different technology and\/or via other providers.<\/strong> <\/p>\n\n\n\n
<\/div>\n\n\n\n
For example:<\/strong>
If your main connection is via fiber from provider A, your backup can be via a wireless LTE or 5G connection<\/strong> from provider B.
If the fiber cable is damaged, your business stays online thanks to an independent wireless connection<\/strong> on a completely different path.<\/p>\n\n\n\n
\n
In short:<\/strong> Diversity not only separates logically, but also physically, thus ensuring real reliability.<\/p>\n<\/blockquote>\n<\/div>\n\n\n\n
\n
$\"Long$ <\/figure>\n<\/div>\n<\/div>\n\n\n\n
Types of diverse internet connections<\/h3>\n\n\n\n
Diversity is not just a technical issue; it encompasses several levels on which the reliability of a connection<\/strong> can be increased<\/strong>. The more of these levels are genuinely separated from one another, the more resilient the connection becomes. The following four stages build on each other, from simple provider separation to full physical diversity.<\/p>\n\n\n\n
$\"Two$ <\/figure>\n\n\n\n
1. Diversity of service providers (ISP)<\/h4>\n\n\n\n
Use different providers<\/strong> for the main and backup lines.
But beware: <\/strong>Some ISPs share the same infrastructure, which means that the desired protection is not available.<\/p>\n\n\n\n
2. Technological diversity<\/h4>\n\n\n\n
Use different transmission technologies<\/strong>, e.g:<\/p>\n\n\n\n
\n
Glass fiber for primary connection<\/li>\n\n\n\n
Copper, LTE or satellite for backup
So you are protected even if one technology fails.<\/li>\n<\/ul>\n\n\n\n
3. Diversity on the last mile<\/h4>\n\n\n\n
Even if the backbone is stable, the “last mile” can become a bottleneck.
Different providers<\/strong> for the last mile ensure additional robustness<\/strong>, even if they use the same path.<\/p>\n\n\n\n
4. Complete diversity<\/h4>\n\n\n\n
The highest level of protection<\/strong>
Different providers for:<\/p>\n\n\n\n
\n
last mile<\/li>\n\n\n\n
IP addresses<\/li>\n\n\n\n
Internet gateways<\/li>\n\n\n\n
Backbones<\/li>\n\n\n\n
Submarine cable<\/li>\n<\/ul>\n\n\n\n
This allows you to achieve maximum redundancy and minimize the risk of simultaneous failure.<\/p>\n\n\n\n
Sounds simple? In practice, it’s complex.<\/h3>\n\n\n\n
Commissioning two providers, combining different technologies, sounds simple.
But in reality, true diversity<\/strong> is a challenge. The reason rarely lies in the technology itself, but in a lack of transparency about the actual routing. Those who do not look closely end up booking two lines that ultimately run over the same route.<\/p>\n\n\n\n
<\/div>\n\n\n\n
The typical stumbling blocks:<\/strong><\/p>\n\n\n\n
\n
Multiple ISPs mean more effort for procurement and administration.<\/strong><\/li>\n\n\n\n
Different technologies require compromises in terms of bandwidth and SLAs<\/strong>.<\/li>\n\n\n\n
Regional regulations<\/strong> can restrict new technologies.<\/li>\n\n\n\n
A lack of market overview leads to wrong decisions<\/strong>, as many ISPs use the same infrastructure.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n\n\n

How SAVECALL supports diverse connectivity<\/h3>\n\n\n\n
<\/div>\n\n\n\n
As a trusted advisor<\/strong>, SAVECALL simplifies the entire process chain:
From procurement<\/a> and management to the optimization of<\/strong> your global connectivity.<\/p>\n\n\n\n
<\/div>\n\n\n\n
With our vendor-neutral approach<\/strong> and a partner network of over 80 carriers worldwide<\/strong>, we will find the best solution for you, including price comparison, SLA analysis and realistic lead times. We check not only the provider name but the actual routing, so that the main and backup lines are truly independent.<\/p>\n\n\n\n
<\/div>\n\n\n\nConclusion:<\/strong> diversity protects against standstill<\/h3>\n\n\n\n<\/div>\n\n\n\n
Reliability is not created by a second line alone, but by genuine independence at every level. Anyone who consistently separates provider, technology and routing protects their operations from exactly the outages that paralyze entire process chains.<\/p>\n\n\n\n
<\/div>\n\n\n\n

Frequently asked questions<\/h3>\n\n\n\n
What does diversity mean in internet connectivity?<\/strong>
Diversity means that an internet connection is secured across multiple, mutually independent network paths that are physically and logically separated. It is not enough to simply book a second line. What matters is that the main and backup connections do not share the same infrastructure, so they do not run over the same PoP, the same submarine cable or the same backbone. Only this genuine separation ensures that a single fault does not hit both connections at once.<\/p> <\/div>
What is the difference between a backup line and diversity?<\/strong>
A backup line is a second connection that takes over when the main line fails. But it only protects if it is truly independent. Diversity goes one step further and ensures that the main and backup lines share no infrastructure at any level, neither provider, technology, last mile nor backbone. Many backup lines unknowingly run over the same physical path, which means the intended protection is lost when it matters most.<\/p> <\/div>
What levels of diversity are there?<\/strong>
Diversity can be implemented on several levels. With provider diversity you use different ISPs for the main and backup lines. With technological diversity you combine different transmission paths such as fiber, copper, LTE or satellite. Last-mile diversity separates the feed to the site. Full diversity finally separates every level: last mile, IP addresses, internet gateways, backbones and even submarine cables. The more levels are separated, the lower the risk of a simultaneous outage.<\/p> <\/div>
Why is true diversity so difficult in practice?<\/strong>
On paper diversity sounds simple: two providers, two technologies. In practice, however, many ISPs share the same physical infrastructure without it being visible from the outside. Without a precise market overview you end up booking two lines that fail together in an emergency. Add to this higher procurement and administration effort, compromises on bandwidth and SLAs, and regional regulations that can restrict individual technologies.<\/p> <\/div>
How do you check whether two lines are truly independent?<\/strong>
The decisive point is the physical route. Two lines are only independent if they share neither last mile, PoP, gateway, backbone nor submarine cable. This cannot be read from the provider name, because many providers rely on the same wholesale input. What is needed is a comparison of the actual routing, ideally with KMZ data or route information. SAVECALL checks this independence vendor-neutral through its carrier network before recommending a solution.<\/p> <\/div>
How does SAVECALL support diverse internet connectivity?<\/strong>
SAVECALL supports the entire process chain, from procurement and management to the optimization of connectivity. Through a vendor-neutral partner network of more than 80 carriers worldwide, we compare providers, technologies and routing, verify genuine independence and deliver price comparison, SLA analysis and realistic lead times. The result is a connection that stays online even when individual paths fail.<\/p> <\/div> <\/div>\n\n\n\n
