Our network

Designed to weather stormy days

Our national network is built with resilience in mind. Through careful design and planning, we've created a network that is intended to handle much more traffic than we are ever likely to see in normal conditions.

Our core and data centre networks benefit from 10Gbps of connectivity and are designed to transparently tolerate the failure of any link or piece of equipment.

This means we're always prepared for when your website goes viral on social media sites or you experience heavy website traffic owing to advertising, product launches, and other media events.

Oh, and of course, we support IPv6 as standard.
