Network & Cloud Infrastructure Since 2011

Founded in 2011, ISIX Communications LLP (trading as i6c) has grown from a specialist network operator into a full-stack infrastructure partner for organisations that can’t afford downtime. Our team combines network engineering, cloud architecture, and cybersecurity expertise to deliver reliable, predictable services rather than one-off projects.

‍

We operate from 483 Green Lanes, London N13, and run our own autonomous systems and IP address space, which gives us direct control over routing, performance and resilience instead of depending entirely on third parties.

i6c provides a portfolio of infrastructure and connectivity services designed to work together as a single, managed platform:

• Managed IT Services – Ongoing management and support for your IT environment: monitoring, maintenance, helpdesk, updates, documentation, and troubleshooting for users and systems.
• Private Cloud – Flexible virtual infrastructure for compute, storage, networking and security, delivered from our own cloud platforms with self-care tools and automation.
• Cloud Access – Secure and high-performance connectivity between your locations, users and cloud workloads.
• Ethernet & MPLS – Point-to-point and multi-site connectivity that links your offices, data centres and cloud environments.
• Private LTE – Dedicated mobile networks to keep remote and teleworking teams online with controlled, secure access.
• IP-transit & BGP routing – High-performance Internet access with optimised routing, low latency and multiple BGP delivery models tailored to your needs.

Our role is to take ownership of the infrastructure so your teams can stay focused on the business:

• We design solutions around your existing infrastructure and applications, rather than forcing a single template.
• We deploy and migrate with clear documentation, change control and realistic timelines.
• We operate and support the environment 24/7, with remote and on-site capabilities and a structured ticketing process.  

Instead of one-off installations, you get a partner that stays responsible for uptime, security, and day-to-day operations.

Under the hood, i6c runs its own network with multiple autonomous systems and extensive IPv4/IPv6 resources, classified as a hosting and content network by major internet registries.  

Our services are built on:

• Interconnected data centre infrastructure, engineered for performance and resilience
• Modern cloud platforms for virtualisation, storage and security
• Networking hardware and software from leading vendors such as Cisco, Huawei, Dell, HPE, Fujitsu and Juniper

This combination lets us deliver predictable performance, controlled latency, and a clear view of your traffic flows end-to-end.

We support organisations that treat connectivity and infrastructure as business-critical rather than optional:

• Companies without an in-house IT department that need a trusted external team
• Organisations with existing IT staff who want to offload operations and routine support
• Service providers and digital businesses that depend on stable, low-latency networks

In all cases, we act as a central point of contact for users, IT stakeholders and third-party vendors.

Customers typically choose i6c for a few simple reasons:  

• End-to-end responsibility – One partner for design, deployment, connectivity and ongoing operations.
• Operational reliability – Proactive monitoring, maintenance and updates to reduce incidents and downtime.
• Security by default – Regular patching, controlled access and network design that reduces attack surface.
• Transparent pricing – Clear, predictable commercial terms that make budgeting for infrastructure straightforward.
• Direct access to experts – Engineers and account managers who understand both the business context and the technical details.

If you’re looking to modernise your infrastructure, simplify operations or improve network performance, i6c is here to help you turn connectivity and cloud into a competitive advantage.
