Multi-Homed Connectivity
Primary and backup nodes connected via redundant 25 Gbps links to tier-1 providers.
BGP routing ensures automatic failover with sub-second convergence.
QUIC Optimization
Custom QUIC stack tuning for Solana's gossip and turbine protocols.
Connection pooling, optimized buffer sizes, and low-latency packet processing.
Geographic Distribution
Primary node: US East (Ashburn, VA). Backup node: US West (San Jose, CA).
Cross-continental redundancy with <500ms inter-node latency.

Security & Operations
Key Management
Vote-only key isolation. Staking keys stored in hardware security modules (HSM)
with multi-signature requirements. No hot wallet exposure.
Backup & Recovery
Automated snapshot management with 7-day retention.
Incremental backups every 6 hours. Disaster recovery tested quarterly.
Uptime & Maintenance
99.9% uptime SLA. Planned maintenance windows communicated 48 hours in advance.
Zero-downtime upgrades via hot-swap failover to backup node.
