ERPC Updates Network Infrastructure Across All Solana VPS Regions, Revisiting L2/L3 Architecture and Bandwidth Utilization Based on Real-World Execution Conditions

ERPC, operated by ELSOUL LABO B.V. (Headquarters: Amsterdam, Netherlands; CEO: Fumitake Kawasaki) and Validators DAO, has completed a network infrastructure update across all regions for its Solana-focused VPS offerings.

With this update, ERPC revisited the network architecture of its virtualization platform based on communication conditions that materially affect results in real Solana operations. The host-side configuration was reorganized at the VLAN, bonding, LACP, and routing levels, enabling environments with multiple NICs to use available bandwidth and parallelism more effectively as actual network throughput.

This update was implemented under the assumption that Solana workloads routinely involve overlapping conditions such as transaction submission, block and shred detection, state update tracking, stream subscriptions, large-scale data transfer, and fluctuations in concurrent connections, where network behavior continues to influence execution outcomes.

Through this update, the host-side L2/L3 configuration was refined to ensure that environments with multiple NICs can utilize bandwidth and parallelism effectively in real operation. As a result, communication conditions are less likely to degrade during periods of sustained high traffic, large data transfers, or overlapping concurrent connections.

Improvements have also been observed in jitter that had affected a subset of nodes. Users who still experience communication instability or jitter on their VPS are encouraged to contact support so the situation can be reviewed individually.

This update has already been applied across all VPS regions.

When considering raw computational performance alone, bare-metal servers tend to deliver higher performance due to the absence of virtualization overhead. Configurations that provide exclusive access to physical CPU, memory, storage, and network resources can achieve the highest performance levels when conditions are aligned.

However, in real Solana operations, not every workload requires large-scale physical servers at all times. The resource requirements for transaction submission, detection, stream processing, backend services, monitoring, and indexing differ by role, and many workloads can operate effectively with moderate CPU and network capacity. In such cases, appropriately sized VPS instances avoid unnecessary resource overhead and offer better operational and cost efficiency.

Additionally, consolidating all roles onto a single large server does not always produce the most stable results. Distributing roles across multiple instances can reduce the likelihood of load spikes overlapping, limit the impact radius of failures, and make staged updates and verification easier. For these reasons, VPS configurations have become a practical and widely used option for many Solana workloads.

VPS and general-purpose cloud VMs have constraints that stem from their underlying architecture. In environments where heavy virtualization layering or excessive over-commitment is applied, resources such as CPU, memory, disk I/O, and network bandwidth are shared among multiple workloads on the same host, making unexpected overhead and performance variability more likely.

Under such conditions, performance can be affected by the load generated by other tenants running on the same host, a phenomenon commonly referred to as interference from neighboring users. In real Solana operations, detection and submission cycles repeat at short intervals, while stream processing and auxiliary workloads continue running without interruption. As a result, even short-lived increases in latency or fluctuations in available bandwidth can directly affect execution outcomes.

In general-purpose cloud environments, network paths are often layered with control, monitoring, and isolation mechanisms, which tend to lengthen communication paths. In addition, outbound traffic from cloud platforms is typically expensive. Given that real Solana workloads commonly generate tens of terabytes of network traffic, outbound bandwidth costs can become a practical operational constraint.

ERPC’s VPS offerings are designed with these real-world operational pain points and requirements in mind, providing a high-quality VPS environment suited for Solana workloads, with configurations that allow large network bandwidth to be used stably and consistently.

In financial markets, execution results have long depended on how quickly information arrives. Since the rise of high-frequency trading, even marginal differences in the delivery time of price data or orders have influenced profit and loss.

To meet these demands, financial networks have evolved over long periods. Data centers were placed closer to exchanges to reduce distance, dedicated links and interconnections were expanded to suppress latency and jitter, and operations were continuously adjusted to maintain stable conditions during peak market volatility. These improvements were not achieved through a single design decision but were accumulated over years of operational refinement.

Over time, emphasis shifted from the size of a financial market itself to the question of where systems should be placed to produce stable results overall. While New York remains the dominant financial market center, the transition to electronic trading and the need for stable, low-latency propagation across the United States changed optimal system placement.

From a geographic perspective, New York’s position on the East Coast favors eastern connectivity but increases maximum distance when covering the West Coast and central regions. To reduce this maximum latency, systems were increasingly placed nearer the center of the continent, leading to the concentration of data centers and network infrastructure in Chicago and the strengthening of dedicated links between New York and Chicago.

A similar pattern has emerged within the Solana network. During the early stages of the network, validator placement naturally clustered near development hubs, as Solana Labs maintained offices in San Francisco and New York. As operations matured and transaction submission, block and shred detection, and state synchronization began to directly influence outcomes, placement criteria shifted toward network topology, reachability, and proximity to other major validators.

As a result, validators and supporting infrastructure have gradually migrated toward network locations that yield more consistent results. Today, Chicago's data center represents the largest concentration of validator stake on the American continent.

In Europe, Solana validator distribution shows the highest concentration in Frankfurt, followed by Amsterdam.

Frankfurt and Amsterdam are located within continental Europe and offer favorable conditions for maintaining balanced reachability across east, west, north, and south. Decades of accumulated international traffic, internet exchange growth, and interconnection density have resulted in multiple short path options and network structures that are less prone to directional bias.

London remains a major city in both financial markets and communications infrastructure. At the same time, its geographic separation from the European mainland introduces submarine segments into continental connectivity, affecting reachability and routing assumptions across Europe.

The current distribution of validators in Europe reflects how these geographic and network structural differences influence operational outcomes, favoring locations where communication conditions remain more stable.

ERPC provides Solana-focused VPS services globally, based on the assumption that network distance and reachability materially affect operational results. Regional availability is not simply an expansion of locations but is designed to allow users to select appropriate placement based on their environment, connectivity, and use cases.

These VPS instances are connected within the same network as ERPC’s Solana infrastructure in each region, including RPC and Geyser gRPC services, enabling zero-distance communication without traversing the public internet.
