Connectivity & Networks

Network resilience.

Keep important services available when a connection, route or piece of equipment fails.

Build backup connectivity and failover around the calls, cloud systems, payments and operational services your teams cannot comfortably lose.

WHEN ONE FAILURE STOPS TOO MUCH

An outage shouldn't take the whole working day with it.

A site can look well connected until one line, router, power source or physical route fails. Then calls drop, cloud systems disappear, payments stop and teams are left finding workarounds, often while customers feel the impact too.

The issue is not always the connection itself. A shared route, single provider or another hidden dependency can still leave critical services exposed.Network resilience reduces that dependency.

The aim is not to promise that nothing will ever fail, but to understand what could stop your teams working, give essential services another route and make the response much clearer when disruption happens.

BUILD RESILIENCE AROUND THE REAL RISK

Choose a backup route that removes the realpoint of failure.

Continuity planning starts by understanding what could fail, then choosing a backup that gives critical services a genuinely different way through. That might be another fixed route, mobile connectivity, satellite or a blend of technologies depending on the site and the impact of downtime.

Secondary fixed routes

Add a second fixed connection with enough capacity to keep priority services running if the primary route fails or local infrastructure is disrupted.

4G or 5G backup

Use mobile connectivity as a backup to keep priority services online where coverage and capacity are strong enough to support them.

Satellite backup

Use satellite as an alternative route where fixed or mobile options are limited, or where extra diversity adds useful resilience.

Blended continuity

Combine fixed, mobile and satellite backup to keep critical services running where one alternative route alone may not be enough.

plan the failover

A second connection is only useful if the plan works.

The right level of resilience comes down to what each connection supports and what would happen if it stopped. At one site, an outage may interrupt email and collaboration; at another, it could stop calls, payments, bookings, cloud apps or services used by customers and the public.

Understanding that impact shows where backup and failover are worth putting in place and what the backup needs to handle. It needs enough capacity, a genuinely separate route and the right switching setup - all tested before anyone has to rely on it.

Identify critical services

Agree which calls, cloud applications, payments or operational systems need to remain available and which traffic can wait.

Match capacity to the priority

Sizethe backup around what must continue rather than assuming every service will run exactly as it does on the primary line.

Automate where it helps

Use suitable routing or SD-WAN rules to move selected traffic to another available connection when the design supports it.

Test before you need it

Run failover tests and repeat them after meaningful changes to circuits, equipmentor applications, so resilience is proven rather than assumed.

WHERE IT HELPS

The bigger the impact of downtime, the stronger the case for resilience.

Resilience matters most where connectivity supports revenue, customer service, critical operations or access to essential systems. The right level of protection depends on the impact of downtime - from a site that can tolerate a short interruption to a customer-facing or public service where every minute offline matters.

Customer service

Keep cloud calls, Teams and contact centre services available, so customers can still reach the right people when the main connection fails.

Care services

Maintain communications, scheduling and essential systems available for patients, residents and care teams when connectivity is disrupted.

Retail and hospitality

Protect payments, bookings, guest WiFi and everyday systems, so teams can keep serving customers while the main connection is restored.

Public sector

Keep systems and communications used by employees, citizens, tenants and service users available when a connection goes down.

Project sites

Give project teams a backup route using mobile, wireless or satellite connectivity when fixed services are delayed, unavailable or disrupted.

Multi-site businesses

Match the level of backup to each location, based on what it supports and how quickly an outage would affect people or services.

Failover in action

What happens when connectivity fails?

A well-designed resilience setup can detect the issue, move important traffic to an alternative route and keep critical services accessible while the primary connection is restored.

01

Primary connection fails

The main circuit becomes unavailable or performance drops below an acceptable level.

02

The network detects the issue

Monitoring identifies the loss of connectivity or degradation affecting the primary route.

03

Traffic moves to backup

Important applications and services are moved onto the available secondary connection.

04

Keep your teams working

Employees continue accessing priority services while the underlying fault is investigated.

05

Primary service returns

Traffic can move back to the preferred connection once normal service and performance are restored.

ONE ACCOUNTABLE TEAM

Built around your network, not just one connection.

Resilience covers more than a spare line. Connections, routing, equipment, power and the services behind them all play a part. Joining the main service, backup and support response together gives one team responsibility for the plan, the testing and the action when something goes wrong.

01

Review the full dependency

Look beyond the circuit to routes, routers, power, applications and the services that must stay available.

02

Back up is based on the risk

Choose fixed, 4G, 5G, satellite or blended connectivity based on the site, risk and likely failure scenario.

03

Test and keep it current

Build in failover and traffic priorities, test them regularly, and review them as your operational needs change.

04

Connect the wider network

Use broadband, SD-WAN and cloud communications to reduce dependencies and protect priority services.

CONNECTED SERVICES

Resilience works across the wider network.

Backup connectivity is only one part of continuity. Primary circuits, routing, applications and communication services all influence what remains available when disruption occurs. Looking at these services together helps make sure the backup route protects the parts of the organisation that matter most.

→

Business Broadband

Choose the primary and secondary fixed services that form the core of the continuity design.

→

SD-WAN

Monitor available connections and route priority traffic more intelligently when performance changes or a circuit fails.

→

Rapid Deployment

Use mMobile or satellite equipment as an emergency or temporary route where fixed services are unavailable.

→

Cloud Communications

nclude cloud telephony and contact centre traffic in continuity planning so customer communication is not forgotten.
