What is Backup Internet?
Backup internet provides a secondary connection that automatically activates when your primary internet fails. Instead of your business going offline during ISP outages, equipment failures, or construction accidents that cut cables, work continues seamlessly on the backup connection.
Also called “internet failover” or “redundant internet,” this critical infrastructure prevents the costly downtime that single-connection businesses experience.
The Cost of Downtime
Internet outages are expensive:
- Employee productivity - Staff can’t access cloud apps, email, or files
- Lost sales - Online orders stop, customers can’t reach you
- Phone system down - VoIP phones require internet to function
- Reputation damage - Missed deadlines and unresponsive service
- Recovery time - Getting back up to speed after an outage
For many businesses, one hour of downtime costs more than a year of backup internet service.
Single vs Redundant Internet
| Feature | Single Connection | With Failover |
|---|---|---|
| Primary Outage Impact | Complete downtime | Automatic switch |
| Employee Productivity | Work stops | Work continues |
| Customer Impact | Can't serve them | No interruption |
| Phone System (VoIP) | Calls drop | Calls continue |
| Cost of Downtime | $$$$ per hour | Minimal to zero |
Backup Internet Options
Cable/Fiber from Different Provider
Best for: Maximum bandwidth backup
- Full-speed backup connection
- Different infrastructure reduces common failures
- Monthly cost for second circuit
- Best if different providers use different paths to your building
Fixed Wireless (Point-to-Point)
Best for: Areas with line of sight to provider
- Completely different infrastructure than wired
- Fast speeds (50-500+ Mbps)
- Weather can affect signal
- One-time equipment plus monthly service
Cellular (LTE/5G)
Best for: Cost-effective backup, locations with good cellular coverage
- Separate infrastructure from wired ISPs
- Fast deployment—works anywhere with cell signal
- Usage-based or unlimited plans
- May have bandwidth limitations
Satellite
Best for: Remote locations with no other options
- Works anywhere with clear sky view
- Higher latency than other options
- Newer services (Starlink) offer good speeds
- Weather can affect service
How It Works
Assessment
Review your uptime requirements, current services, and available options in your area.
Design
Select backup connection type and configure failover rules and priorities.
Installation
Install backup circuit and configure failover equipment.
Testing
Verify failover works correctly and recovery is automatic.
Monitoring
Ongoing monitoring alerts you when failover occurs.
How Failover Works
- Monitoring - Router continuously checks primary connection health
- Detection - Outage detected (ping failures, bandwidth drops)
- Switching - Traffic automatically routes to backup connection
- Recovery - When primary returns, traffic switches back automatically
Advanced setups can detect degraded connections (not just complete failures) and make intelligent routing decisions based on application requirements.
Key Benefits
Automatic Failover
When primary internet fails, backup kicks in automatically—no manual switching.
VoIP Protection
Phone calls stay connected even during internet transitions.
Cloud App Access
Continue using cloud applications and services without interruption.
Diverse Paths
Different carriers and technologies reduce single points of failure.
Load Balancing
Optionally use both connections together for increased bandwidth.
Real-Time Monitoring
Know immediately when failover occurs and when primary recovers.
Frequently Asked Questions
What backup internet options are available?
Common options include: secondary business cable or fiber from a different provider, fixed wireless (point-to-point), cellular/LTE/5G failover, and satellite. The best choice depends on your location, budget, and uptime requirements. We recommend diverse technologies (e.g., fiber primary with LTE backup) for maximum resilience.
How fast is the failover?
With proper equipment, failover typically occurs within 30 seconds of detecting an outage. Some advanced setups can failover in under 10 seconds. VoIP calls may briefly drop during transition, but reconnect automatically.
Can I use both connections at the same time?
Yes, most SD-WAN and dual-WAN routers support load balancing where both connections are used simultaneously. This increases total bandwidth and means one connection is already active when the other fails, making failover even faster.
What equipment do I need?
You need a dual-WAN router or SD-WAN device capable of automatic failover. If you have a single-WAN firewall, we can add a failover device in front of it. We'll recommend the right solution based on your existing infrastructure.
How do I know when failover occurs?
Our monitoring systems alert you immediately when failover activates and again when the primary connection recovers. You'll know exactly when outages occur and how long they lasted.
Is cellular/LTE backup fast enough?
For most business operations, yes. Modern LTE provides 20-50 Mbps which handles email, cloud apps, VoIP, and web browsing well. It may not support bandwidth-intensive activities like large file transfers or video production, but keeps your business operational during outages.
