The True Cost of Going Offline

When your internet goes down, it's not just an inconvenience — it's a business emergency. Consider what stops working:

• VoIP phones — customers can't reach you, you can't make calls
• Card payments — lost sales at the point of purchase
• Cloud applications — Microsoft 365, accounting, CRM all go offline
• Email — no sending or receiving
• CCTV — cloud cameras stop recording

For a Northern Ireland business with 10 employees, one hour of downtime can cost £500-2,000 in lost productivity alone — before you count lost sales and customer frustration.

Building a Resilient Internet Strategy

The key principle is diversity — using different technologies from different providers over different infrastructure. If one fails, the others keep you running.

Level 1: Basic Resilience (£15-30/month)

Add a 4G/5G SIM failover to your existing broadband. This is the single most impactful step any business can take:

• A dual-WAN router with a data SIM
• Automatic switchover when broadband fails
• Uses completely different infrastructure (mobile vs fixed-line)
• Protects against cable cuts, exchange faults, and provider outages

Level 2: Enhanced Resilience (£50-100/month)

Add a second fixed-line connection from a different provider, plus 4G/5G backup:

• Primary: Fibre broadband (e.g., BT/Openreach)
• Secondary: Different provider or technology (e.g., Virgin Media cable)
• Tertiary: 4G/5G SIM as last resort
• SD-WAN or dual-WAN router manages all three connections

Level 3: Maximum Resilience (£200-500/month)

For businesses where downtime is simply not acceptable:

• Primary: Leased line with SLA-guaranteed uptime
• Secondary: Fibre broadband from different provider
• Tertiary: 4G/5G or Starlink satellite
• SD-WAN with intelligent traffic routing and load balancing

Beyond Internet: Complete Business Continuity

Phone System Resilience

If you're using hosted VoIP, your phone system is in the cloud — it survives even if your office burns down. But you still need internet to access it. With failover in place, your phones stay working through any broadband outage. Additionally:

• Configure automatic call forwarding to mobiles as a last resort
• Ensure your VoIP provider has geographic redundancy in their data centres
• Keep mobile phones charged and ready as backup communication

Cloud Access

With internet failover, your team maintains access to cloud applications. But also consider:

• Offline access to critical documents (Microsoft 365 offline mode)
• Local backups of essential data
• Mobile hotspot capability on business phones as emergency backup

Choosing the Right Failover Technology

The best backup depends on your location and primary connection:

• Urban Belfast: 5G failover — fast speeds, low latency, excellent coverage
• Suburban NI: 4G failover — reliable coverage, cost-effective
• Rural NI: Starlink or 4G with external antenna — where mobile coverage is weak
• Critical operations: Leased line + 4G/5G — guaranteed uptime with mobile backup

Testing Your Continuity Plan

• Test failover quarterly by disconnecting your primary broadband
• Verify VoIP phones work on the backup connection
• Check card payment terminals function during failover
• Ensure cloud applications remain accessible
• Time the switchover — it should be under 30 seconds
• Review and update your plan annually
