Types of Internet Redundancy
Active-Active Redundancy
$$$ High CostHow it works: Two connections actively share traffic load
Failover time: Instant (0 seconds)
Best for: Mission-critical operations, e-commerce, call centers
- Load balancing increases total bandwidth
- No downtime during failover
- Requires advanced networking equipment
Active-Passive Redundancy
$$ Medium CostHow it works: Backup connection activates when primary fails
Failover time: 30 seconds - 2 minutes
Best for: Most SMBs, professional services
- Lower cost than active-active
- Simple to implement
- Backup connection sits idle normally
Wireless Backup (4G/5G)
$ Low CostHow it works: Cellular connection as emergency backup
Failover time: 1-3 minutes
Best for: Small offices, temporary backup
- Quick to deploy
- Works during cable/fiber cuts
- Limited bandwidth and data caps
Failover Methods Explained
- DNS Failover: Changes DNS records to redirect traffic (5-15 minutes)
- BGP Failover: Automatic route advertisement changes (instant-30 seconds)
- Hardware Failover: Router/firewall detects and switches connections (30 seconds-2 minutes)
- SD-WAN Failover: Software-defined intelligent path selection (instant)

Florida-Specific Considerations
Hurricane Season Preparedness
Florida businesses face unique challenges from June 1 - November 30 annually.
Hurricane-Resistant Redundancy Strategy:
- Diverse Physical Paths: Ensure primary and backup use different fiber routes
- Underground vs Aerial: Mix underground fiber with aerial cable/wireless
- Different Central Offices: Connections should terminate at different ISP facilities
- Generator Backup: 48-72 hour fuel capacity recommended
- Satellite Backup: Consider Starlink Business for extreme scenarios
Pre-Hurricane Checklist:
- Test failover procedures monthly during hurricane season
- Verify backup power systems and fuel levels
- Document emergency contact numbers for all ISPs
- Enable remote management capabilities
- Backup configurations to cloud storage
Regional Vulnerability Analysis
Region | Primary Risk | Recommended Primary | Recommended Backup |
---|---|---|---|
South Florida (Miami-Dade) | Hurricanes, flooding | Underground fiber | 5G business / Satellite |
Tampa Bay | Storm surge, lightning | Fiber (elevated routes) | Cable + 5G |
Orlando (Central) | Construction, growth | Fiber | Cable (different route) |
Jacksonville | Tropical storms | Fiber | Fixed wireless |
Panhandle | Hurricanes, tornadoes | Cable | 5G / Satellite |
Implementation Strategies
Step-by-Step Implementation Guide
- Assess Current Vulnerabilities
- Document current connection type and path
- Identify single points of failure
- Calculate downtime costs for your business
- Design Redundancy Architecture
- Choose active-active vs active-passive
- Select diverse connection types
- Plan IP addressing and routing
- Select Providers
- Verify different physical infrastructure
- Confirm SLAs align with needs
- Negotiate multi-connection discounts
- Procure Equipment
- Dual-WAN capable router/firewall
- Appropriate licensing for features

Cost Analysis & ROI
Redundancy ROI Calculator
Example: Medium Business (25 employees)
Current Situation:
- Average downtime: 12 hours/year
- Cost per hour down: $3,000
- Annual downtime cost: $36,000
Redundancy Investment:
- Setup costs: $3,000 (equipment + installation)
