UK Connectivity Map

A business' network is the backbone of its IT infrastructure. Availability, resiliency and cybersecurity are all critical to keep your customers online and support their increasing demands. The transition to hosted platforms is a seismic shift in how businesses operate, and the implications of downtime are greater than ever before. Therefore, it's essential to get it right first time and the Vaioni Network delivers against all these key factors, sitting at the core of every product and service we deliver.

Our Core Network

Our core network proves our qualities as a leading network operator. Built using carrier-grade infrastructure in datacentres across London and Manchester, we’re constantly innovating to match the needs of the always-connected workforce. All our customer traffic uses this network and we're proud to boast near 100% uptime since 2015!

The Vaioni Ethernet Network (VEN)

VEN connects over 100 cities and towns, bringing competitive and feature-rich connectivity up to 10Gb to over 350,000 UK postcodes. Annual investments and a culture of constant innovation ensures we increase our reach and evolve our services, enabling you to deliver services to even more businesses and ensure happier customers.

Our Aggregated Network

While we enjoy strategic partnerships with the UK's leading Ethernet providers, (including BT Wholesale, TalkTalk Business, Virgin Media Business and Vodafone) we’re not wedded to any single provider. We've connected their networks with our own to ensure your customers have access to the broadest footprint, the widest choice of speeds and most customisable technologies, at the best possible price.

Put simply, wherever your customers are, we can connect them.
