Our own autonomous system
Direct network operation under our RIPE ASN gives us greater control over routing and service delivery.
IT Communications
Our Network
Explore IT Communications’ resilient UK voice network, two London data centres and two diverse 100Gb fibre routes providing 200Gb usable capacity.
Infrastructure under our control
A UK communications network built for dependable service.
IT Communications operates its own dedicated network under RIPE autonomous system number AS203416. Each data centre uses at least two IP transit providers, with public peering at LINX and private peering supporting diverse BGP routing.
The platform operates across two London data centres with a 100Gbps network backbone and diverse inter-site connectivity.
Core network
Resilience at every layer.
Independent routing, owned address space and geographically separated infrastructure provide a strong foundation for voice, connectivity and hosted services.
Diverse BGP routing
Multiple carrier relationships provide alternative upstream paths and reduce dependence on a single network.
Backbone capacity
High-capacity infrastructure supports the communications and hosted services delivered across the platform.
London resilience
Services operate across Central London and Docklands locations joined by two diverse high-capacity routes.
Two London operating locations
Purpose-built environments for critical infrastructure.
Each site contributes physical security, resilient power and carrier access to the wider network design.
