ERPC Completes 10Gbps Network Upgrade at Chicago Data Center, Optimizing East–West Connectivity as a Core U.S. Hub with Dedicated Solana Fiber Network
ERPC Completes 10Gbps Network Upgrade at Chicago Data Center, Optimizing East–West Connectivity as a Core U.S. Hub with Dedicated Solana Fiber Network
ELSOUL LABO B.V. (Headquarters: Amsterdam, the Netherlands, CEO: Fumitake Kawasaki) and Validators DAO have completed maintenance work at the ERPC Chicago Data Center and officially launched 10Gbps high-speed connectivity across all servers.
This upgrade significantly enhances communication efficiency between the U.S. Midwest and both coasts, strengthening Chicago’s role as a central hub directly connected to the Solana dedicated fiber network, DoubleZero.
Strategic Significance of the Chicago Region
Located in the U.S. Midwest, Chicago functions as a key transit point connecting the East and West Coasts.
Its central position allows it to serve as a national network hub, enabling efficient, low-latency routing across the continent.

With this 10Gbps upgrade, ERPC has built a highly resilient infrastructure capable of maintaining stable response even during peak traffic periods.
As a regional relay and aggregation hub, Chicago now contributes to improved network quality and reliability across the entire global infrastructure.

High-Speed East–West Direct Routes via DoubleZero
The Chicago (CHI) Data Center is directly linked to Salt Lake City (SLC) and Los Angeles (LAX) through DoubleZero, a 100Gbps dedicated fiber network purpose-built for Solana.
This minimizes congestion and route changes typical of public internet paths, enabling stable, low-latency data transmission between the East and West.

Chicago also maintains high-speed connections to New York via major backbone networks, extending the benefits beyond the U.S. to global Solana developers and applications.
The DoubleZero network forms a dedicated, validator-to-validator backbone that enhances the overall performance and reliability of the Solana ecosystem.

Technical Upgrade Details
The network bandwidth across the Chicago region has been unified to 10Gbps per server.
Latency-based dynamic routing continuously monitors real-time ping values to select the optimal path, while nftables-based protection logic automatically detects and mitigates abnormal or excessive traffic to maintain system stability.

- Unified all servers to 10Gbps connectivity
- Dynamic routing based on real-time latency measurements
- Strengthened nftables security layer for live anomaly filtering
- Updated bandwidth limits for RPC, gRPC, and Shredstream
- Improved throughput and response stability under high concurrency
The bandwidth expansion also increases real-time multicast capability, enabling more data to be distributed efficiently to a greater number of projects and developers simultaneously.
Benefits for Developers and Projects
- All ERPC services now run on 10Gbps bandwidth (no price changes)
- Stable connectivity even under heavy load
- Reduced packet loss and route fluctuation via DoubleZero
- Improved communication efficiency and response times globally
Solana RPC Bundle Plan
The ERPC Bundle plan offers unified access to HTTP, WebSocket, gRPC, and Shredstream endpoints.
It allows flexible migration or parallel usage between RPC and Shredstream, enabling developers to enhance performance without changing their existing applications.

The gRPC service supports unrestricted filtering and is compatible with Devnet and Testnet, providing a seamless development-to-production workflow for Solana applications.
EPYC VPS in the Same Network
Within the Chicago region, ERPC also provides EPYC VPS instances optimized for Solana workloads—hosted in the same network as RPC, gRPC, and Shredstream endpoints.
This close physical and network proximity minimizes round-trip latency and reduces jitter between application servers and Solana data streams.

Future Expansion
ERPC continues to strengthen existing data centers while expanding global edge locations.
By minimizing network distance between users and endpoints, ERPC ensures that projects and developers worldwide can connect via the shortest and most efficient routes.

As the U.S. spans vast east–west distances, each coast serving as a gateway to other continents, this regional reinforcement directly contributes to the overall network quality of the Solana ecosystem.
ERPC will continue optimizing its hardware, virtualization, and network layers to enhance the performance and developer experience across Solana’s global infrastructure.

Challenges Addressed by ERPC and Validators DAO
- Transaction failures and latency fluctuations in conventional RPC environments
- Performance throttling by general-purpose infrastructure providers
- Network distance and its significant impact on data transmission quality
- Limited access to high-quality infrastructure for smaller projects
Through the development of the open-source Solana NFT card game project Epics DAO, we recognized the challenge of accessing stable and high-performance Solana environments for developers.
That experience led to the creation of ERPC and SLV, providing developers with accessible, high-quality infrastructure optimized for Web3 and financial workloads.
