When the stakes are high in a connection-critical world

Network Resilience

The world depends on digital technology: for business, for health, for peace.

Connectivity is fundamental for society, and an outage caused by accident, conflict, or natural disaster can destabilise a nation.

Resilience has become the new non-negotiable for communication networks, alongside speed and capacity.

Discover how Satellite has become a backbone of our always-on era.

Why networks fail


Natural disaster

As the world grapples with climate change, terrestrial systems can be vulnerable to force majeure, such as earthquakes, flooding and hurricanes.



In a time of geopolitical tensions, ground infrastructure, such as subsea cables, may become a target for military operations or the collateral damage of war.


Technical faults

No technology is immune to failure or outages, which can bring down networks with a single point of failure.



Sometimes, a network outage can’t be predicted – in 2011, the entire country of Armenia lost internet connectivity after a copper scavenger sliced a cable.

Repair is not resilience

The consequences of a network outage range from lost business to lost life. Repair isn’t always easy, particularly in a disaster zone or a technically complex location. A severed subsea cable can take weeks to fix, involving specialist vessels and voyage time to fetch spare parts.

Permanent Satellite Backup

Reputation damage, unhappy customers, financial loss — the stakes are too high for network operators to operate with a single point of failure.

Satellite failover solutions can seamlessly pick up dropped terrestrial links so business and government operations can go uninterrupted.

Constant connection

Discover how SES’s multi-orbit fleet works with your primary terrestrial link to maintain constant connection in all circumstances.

Resilience means more than 'on' or 'off'

Resilience is not just about backup but performance. It means video meetings that never drop, a financial trade processed in vital milliseconds…

Software-defined wide area network (SD-WAN) systems send traffic on the most efficient path in a combined satellite and terrestrial network. This might mean routing latency-sensitive calls over fibre optic while sending emails and web traffic via satellite. If one link experiences issues, SD-WAN automatically shifts more traffic to the optimal pathway.

Who decides ‘optimal’? With SD-WAN, governments, Telcos, and businesses define what works for their needs at any given time.

Multi-orbit – The key to satellite resilience

Satellite may be failsafe to fibre. Connection is vital to use cases such as military operations or the safe running of a desert oilfield.

Resilience means multiple orbits and frequency bands working together across a single seamless architecture.

O3b mPOWER is the first and only system to achieve this hybrid system resilience.

Resilience in action for Vodafone Cook Islands

The O3b mPOWER satellite constellation provides backup to The Cook Islands’ undersea cable connection while delivering digital inclusivity to the archipelago’s outer reaches.


On-demand backup

A natural disaster can bring down communications when they are needed most.

In the critical hours and days following an earthquake or flood, it is essential for first responders and aid workers to coordinate rescue and for families to tell loved ones they are safe.

Both portable and fixed satellite backup services can quickly stand in for damaged infrastructure.

Backup Services

Different types of backups explained: from portable to fixed solutions.

Comms on the Pause (COTP) - Your network delivered

When infrastructure fails – or isn’t there in the first place – Comms on The Pause (COTP) brings the network to you.

COTP sets up portable ground equipment where capacity is needed the most, from disaster zones to temporary events like outdoor music festivals.

It is also a cost-effective way for network operators to test demand for terrestrial infrastructure, for example, by bringing 5G to a 4G area for a trial period.

Overcoming commercial restrictions to resilience

There is no such thing as one-size-fits-all resilience, and customers should not have to pay for services they do not need. SES has developed a model that governments, telcos, and businesses can tailor to their individual needs.

Flexibility: Organise resilience around your needs and budget
Link agility: Dynamically balance forward and return capacity
Link portability: Move capacity around your network as demands change
Multi-orbit and multi-operator networks: Combining GEO, MEO, and LEO under a single agreement
Customer-centric Service Level Agreements: Guaranteeing the most critical network capabilities

Certainty in an uncertain world

In a fast-changing world, investing in resilient communications is a necessity.

We can’t predict events, but we can do everything in our power to be prepared.
