Top-tier RPC providers are now committing to 99.9-99.99% availability with actual SLAs. This is a massive maturation of blockchain infrastructure.
What Changed in 2026
Before: Best effort uptime, no guarantees
Now: SLA-backed 99.99% uptime with financial penalties for breaches
Leading providers:
- GetBlock: 99.99% availability guarantee
- Chainstack: 99.9% SLA with enterprise support
- Ankr: 99.9% commitment across 70+ chains
Why This Matters
For production apps: You can finally build enterprise-grade dApps with reliability guarantees.
For businesses: RPC downtime is now a vendor accountability issue, not just bad luck.
For developers: Infrastructure failure isn’t your fault anymore.
The Technical Requirements
To achieve 99.99% uptime:
- Geographically distributed nodes
- Automated failover systems
- Load balancing across regions
- Real-time health monitoring
- Multi-provider redundancy
Cost: Premium pricing but worth it for production workloads.
What I’m Doing Differently
My zkEVM project now uses multi-provider RPC with automatic failover:
- Primary: Chainstack (fastest)
- Secondary: GetBlock (reliability)
- Tertiary: Self-hosted (last resort)
Result: Zero downtime in 3 months of production.
Question: Are you using SLA-backed RPC providers yet?
