InMotion Hosting has meticulously designed its data center network to incorporate advanced redundancy and failover protocols. These protocols are fundamental in ensuring continuous operation and high availability of their services, even in the face of unexpected hardware or network failures.
Let’s have a closer look at the technical specifics of how these protocols function within their data center infrastructure.
Redundancy in Power and Cooling Systems
- Uninterruptible Power Supplies: InMotion Hosting employs a block redundant UPS configuration with N+1 redundancy. This means that for every unit of power supply equipment in use, there’s an additional unit on standby. In practical terms, if a UPS unit fails, the standby unit immediately takes over, ensuring uninterrupted power supply.
- Standby Power Generators: The data centers are equipped with multiple diesel generators, each capable of generating 3,000 kW of power, configured in an N+1 redundancy. This setup ensures that in the event of a utility power failure, these generators can provide backup power without any service interruption.
- Cooling Systems: The data centers utilize high-efficiency Indirect Evaporative Cooling Units with Indirect Airside Economizers, also configured for N+1 redundancy. This cooling redundancy is crucial for maintaining optimal temperatures and preventing overheating of critical infrastructure.
Network Infrastructure Redundancy
- Multiple Data Centers: InMotion Hosting operates three strategically located data centers – in Los Angeles, Ashburn, Virginia, and Amsterdam. This geographical diversity allows for the distribution of network load and provides an additional layer of redundancy.
- Load Balancing: Network load balancing is a critical component. It distributes network traffic across multiple servers, preventing any single server from becoming a bottleneck. This not only optimizes performance but also ensures that in the event of a server failure, traffic can be rerouted to other operational servers seamlessly.
- Network Peering: InMotion Hosting maintains peering relationships with major networks and ISPs. This setup facilitates direct traffic exchange, which not only reduces latency but also adds an extra redundancy layer, as traffic can be rerouted through different peers if needed.
Failover Protocols
- Automatic Failover Mechanisms: InMotion Hosting’s network is designed to automatically detect failures in the system. Upon detection, the failover mechanisms are triggered, rerouting traffic to operational hardware or network paths, thereby minimizing downtime.
- Smart Routing Technology: This technology plays a pivotal role in traffic management. It continuously analyzes the network path, ensuring that data is routed through the most efficient and least congested paths. In the event of a path becoming unavailable, smart routing instantly redirects traffic to the next best available route.
- Internet Exchange Points: The close proximity of their data centers to crucial IXPs ensures that there are multiple routing paths available for data. This ensures low latency and high resilience, as traffic can be rerouted through various IXPs if necessary.
In summary, the redundancy and failover protocols in InMotion Hosting’s data center network represent a comprehensive approach to achieving high availability and resilience. By integrating redundancy at every level – power, cooling, network infrastructure – and employing automatic failover mechanisms, InMotion Hosting ensures that their hosted websites and applications remain operational and accessible, even in the face of technical adversities. This technical foresight and infrastructure investment underscore InMotion Hosting’s commitment to providing reliable and uninterrupted web hosting services.

Advantages of InMotion Hosting’s Redundancy and Failover Protocols
- Enhanced Reliability and Uptime: The N+1 redundant power and cooling systems ensure that there is always a backup in case of component failure, significantly reducing the probability of service interruptions. This directly translates to enhanced reliability and consistent uptime for hosted websites and applications.
- Optimized Performance and Reduced Latency: The strategic geographic distribution of data centers, coupled with load balancing and efficient network peering, results in optimized performance. This setup minimizes latency, as data travels shorter distances and through less congested paths, ensuring faster website load times and smoother user experiences.
- Scalability and Flexibility: InMotion Hosting’s network infrastructure is designed for scalability. The ability to handle increased traffic and data loads seamlessly aligns with the growing demands of businesses, providing flexibility in resource allocation and service scalability.
- Automatic Traffic Rerouting: Smart routing technology and automatic failover mechanisms ensure real-time traffic management. In the event of a path failure, traffic is immediately rerouted to the most efficient alternative, maintaining operational continuity and avoiding potential downtime.
Limitations and Considerations
- Complexity and Management Overhead: The intricate design of redundancy and failover systems adds layers of complexity to the network infrastructure. This requires a higher level of expertise for management and maintenance, potentially leading to increased overheads in terms of human resources and technical management.
- Cost Implications: Implementing and maintaining such high-level redundancy and failover protocols can be cost-intensive. These costs might reflect in the pricing of the hosting services, which could be a consideration for small to medium-sized businesses.
- Latency in Failover Activation: While automatic failover systems are designed for immediate response, there can be minimal latency during the switchover process. This brief period, although typically negligible, might impact services that require real-time data processing.
- Potential for Over-reliance: There’s a risk of becoming over-reliant on automated systems, which might lead to reduced vigilance in manual monitoring and maintenance. Continuous human oversight remains crucial to ensure the systems function as intended.
In conclusion, InMotion Hosting’s advanced redundancy and failover protocols provide robust solutions for high availability, performance optimization, and scalability, albeit with considerations in complexity, cost, and the need for vigilant oversight. Understanding these aspects is crucial for businesses to make informed decisions regarding their web hosting needs.
