Telehouse Canada’s Data Centre Interconnect (DCI) provides dedicated, low-latency connectivity between 151 Front Street West, 250 Front Street West, and 905 King Street West. With access to over 200 on‑site network and service providers, customers can interconnect with partners that enable global data centre reach and infrastructure expansion.

Infrastructure deployed across multiple facilities operates as a unified environment, while maintaining the advantages of physical separation.

Network Architecture and Path Diversity

Telehouse Canada’s DCI architecture is designed with physical path diversity built into every layer of the network. 

Each dark fibre ring follows separate physical routes between facilities, reducing the risk of a single event impacting connectivity across the campus. This separation ensures that infrastructure deployed across multiple locations remains connected even in the event of fibre cuts, localized outages, or infrastructure failures along a single route. 

Because both rings operate simultaneously, organizations can design active-active or active-passive configurations based on their infrastructure requirements. This flexibility allows network architects to align interconnection design with internal availability targets rather than adapting to external network limitations. 

What DCI Enables

Data Centre Interconnect (DCI) supports infrastructure architectures that depend on reliable, high-capacity connectivity between sites. 

Multi-Site Redundancy

Applications and data can be replicated across facilities, allowing operations to continue from alternate locations if required.  

Capacity Expansion Without Re-Architecture

As demand increases, organizations can extend infrastructure into additional facilities while maintaining a single operational environment across sites. 

Access to the Full Connectivity Ecosystem

Each Telehouse Canada location provides access to carriers, cloud platforms, and internet exchanges. Through DCI, clients benefit from the combined ecosystem across all facilities without deploying infrastructure in each location. 

Low-Latency Inter-Site Performance

For latency-sensitive workloads such as distributed databases, real-time processing, and AI environments, private interconnection removes the variability associated with public internet routing. 

Global Data Centre Reach

By interconnecting with on‑site network and service providers, customers can extend connectivity beyond the Telehouse Canada campus to reach data centres and cloud environments globally. 

Common DCI Deployment Use Cases

Telehouse Canada’s Data Centre Interconnect supports a range of deployment models across enterprise and high-performance environments. 

Disaster Recovery and Business Continuity

Infrastructure can be distributed across multiple facilities with continuous data replication between sites. In the event of a disruption, systems can fail over to a secondary location without relying on public network paths. 

Hybrid and Multi-Cloud Connectivity

Organizations operating hybrid or multi-cloud environments can use DCI to maintain consistent connectivity between on-premises infrastructure and cloud-connected systems across multiple locations. 

AI and High-Performance Workloads

AI inference and data-intensive workloads often require high-throughput communication between compute, storage, and networking resources. DCI provides the low-latency, high-capacity links needed to support these environments without bottlenecks.

Enterprise Application Distribution

Applications can be distributed across facilities to improve performance, manage load, and isolate workloads while maintaining synchronized operation between environments. 

Built on a Dual Dark Fibre Ring

Telehouse Canada’s DCI service is built on two diverse 864-count dark fibre rings connecting all three Toronto facilities. 

This architecture delivers: 

  • High-capacity bandwidth  
  • Physical path redundancy  
  • Consistent, low-latency performance  
  • Access to diverse connectivity ecosystem 

Because traffic moves across dedicated dark fibre network rather than public networks, data transfer between locations remains predictable, secure and redundant 

In the event of a disruption along one path, traffic automatically reroutes across the secondary ring without manual intervention.
