High Availability Setup

Learn how to create ultra-resilient load balancers with NovaNode's multi-region configuration.

Understanding High Availability

NovaNode leverages Fly.io's global infrastructure to provide N+1 redundancy within each region and optional multi-region failover for maximum uptime.

Within-Region Redundancy

Every NovaNode deployment maintains at least one spare instance in each region to handle failover if a node becomes unhealthy.

Cross-Region Failover

With multi-region deployments, traffic automatically routes to the next closest region if an entire region experiences issues.

Configuring Multi-Region Deployment

1. During load balancer creation, select multiple regions
2. We recommend selecting at least 3 regions for maximum reliability:
   • One near your primary user base
   • One on a different continent as backup
   • One additional region for comprehensive coverage

Monitoring Region Health

The NovaNode dashboard provides real-time visibility into the health of each regional deployment, showing:

• Active nodes per region
• Request volume by region
• Response time metrics
• Error rates by region

Advanced Configuration

For custom high-availability configurations using Caddy's advanced directives, see our Caddy Configuration Examples page.

Disaster Recovery

NovaNode automatically handles most failure scenarios without any intervention. However, in extreme cases, you can:

1. Add additional regions through the dashboard
2. Force redeployment to refresh all instances
3. Contact support for assistance with major outages
