What Happens to Your Business When the Internet Goes Down?

For most Birmingham businesses, an internet outage is not an inconvenience — it is a business stoppage. VoIP phones go silent. Microsoft 365 becomes inaccessible. Cloud-hosted applications stop. Video calls fail. Payment terminals go offline. For every hour your internet is down, your business is losing money — and potentially losing clients. 

Sentinel SecureTech designs and manages internet failover and backup connectivity solutions for businesses across Birmingham and the UK. When your primary connection fails — whether a leased line or business broadband — failover activates automatically within seconds. Your team keeps working. Your customers see nothing. We manage the failover infrastructure alongside your primary connectivity as a single service. 

What Happens to Your Business When the Internet Goes Down?

A 4G failover router connects to the mobile network the moment your primary connection fails. Failover triggers automatically — no one needs to plug anything in, switch anything on, or call anyone. For most Birmingham businesses, 4G failover is the fastest and most cost-effective backup solution. Monthly cost is low; it only uses meaningful data when it is active. 

What’s included: 

  • 4G failover router — installed and configured alongside your primary connection 
  • Automatic failover — triggered within seconds of primary connection failure 
  • Multi-network SIM — automatically connects to the strongest available mobile network 
  • Monitoring — we see the failover event and begin primary circuit fault resolution immediately 
  • Fixed monthly cost — regardless of how often failover activates 

5G Failover

Where 5G coverage is available at your site, 5G failover provides speeds approaching or exceeding leased line performance as a backup circuit. Ideal for high-demand Birmingham businesses where 4G speeds would be insufficient to maintain full operations during a primary circuit outage. 

Secondary Fibre Circuit

For businesses where mobile failover is not sufficient — financial services, healthcare, contact centres — a secondary fibre circuit provides dedicated backup capacity on a physically separate route from your primary connection. If the primary circuit fails — even due to a physical fibre cut — the secondary circuit continues to carry traffic. 

FTTP Backup for Leased Line Customers

For leased line customers, an FTTP business broadband connection provides cost-effective backup capacity at speeds sufficient to maintain Microsoft 365, VoIP, and core cloud applications during a primary circuit outage. Lower cost than a full secondary leased line, with better performance than 4G for bandwidth-heavy operations. 

SD-WAN with Built-In Failover

If you are running SD-WAN, failover is built into the platform — it intelligently routes traffic across all available connections at all times, with automatic path switching when any circuit degrades or fails. This is the most sophisticated and resilient failover approach for multi-site businesses.

Why UK Businesses Choose Sentinel SecureTech for Backup Connectivity

Our backup connectivity solutions are designed and managed alongside your primary leased line or business broadband — by the same team. When your failover activates, we already know about it. We are already working on the primary fault. You do not need to call two separate suppliers. 

Automatic — No Human Intervention Required

Our failover solutions activate without any action from your team. The router detects primary circuit failure and switches to the backup path within seconds. Your team may not even notice.

We Monitor the Failover Event

When failover activates, our network operations centre receives an alert immediately. We begin fault management on the primary circuit at the same time — so recovery is already in progress before you have noticed anything is wrong.

Right-Sized for Your Risk

A Birmingham legal firm has different continuity requirements to a small retail shop. We design failover solutions around your specific business risk — the cost of downtime, your recovery time objective, and your budget.

Fixed Monthly Cost

Backup connectivity is priced on a fixed monthly basis. There are no activation charges when failover triggers and no usage-based billing surprises.

How Does Backup Connectivity Installation Work?

Resilience Assessment

We review your current connectivity setup and business continuity requirements — identifying the right failover solution for your risk profile and budget. No obligation.

Solution Design & Quote

We design your failover architecture and provide a clear fixed-price quote. For 4G failover, this is typically a straightforward installation. For secondary fibre circuits, we include a full installation plan.

Installation & Testing

We install and configure your failover solution alongside your primary connection, then test it — deliberately failing the primary connection to confirm automatic failover works correctly. You see the test result before we leave.

Monitoring & Management

From installation, we monitor both your primary and backup connections continuously. If failover activates, we know immediately and begin fault resolution on the primary circuit without waiting for you to call.

Your Questions About Internet Failover for UK Businesses — Answered

How quickly does internet failover activate?

Automatic internet failover activates within seconds of primary circuit failure. 

Our failover routers continuously monitor the primary connection and switch to the backup path as soon as a failure is detected — typically within 5 to 30 seconds depending on configuration. For most business applications, this is fast enough that users experience no visible interruption. 

4G failover uses the mobile network. A secondary fibre circuit is a dedicated physical backup connection. 

4G failover is lower cost and sufficient for most business applications during an outage. A secondary fibre circuit provides dedicated capacity on a physically separate route — appropriate for businesses with high bandwidth requirements or where mobile coverage is poor. We recommend the right option based on your specific site and risk profile. 

4G failover for UK businesses typically costs between £30 and £80 per month on a fixed basis. 

Secondary fibre circuits are priced as a standalone connection — cost depends on speed and location. All our failover solutions are fixed monthly pricing with no activation charges when failover triggers. We provide a free assessment and written quote before any commitment. 

Yes — our failover solutions are designed to work alongside your existing primary connection. 

We install the failover router in parallel with your current setup. No changes to your primary connection are required. The failover router monitors your primary circuit and activates automatically when needed.

Yes — properly configured failover maintains VoIP services during a primary circuit outage. 

VoIP quality over 4G is generally sufficient for business calls during an outage. For businesses with high call volumes or where call quality is critical, we recommend 5G failover or a secondary fibre circuit to ensure adequate bandwidth for your phone system. We test VoIP functionality as part of every failover installation.
