B4RN’s Resilient 400G Network in Northern England goes Live

This will see B4RN’s backhaul speeds increase tenfold to 400Gbps around the entire ring allowing them to increase network bandwidth and decrease network latency deeper into rural communities. With this upgrade we are securing the long-term operation of the core network, allowing new communities to connect, and additional services such as transit and ethernet services to local businesses and the wider telecoms industry. 

B4RN has a completely 100% subsurface network, it’s all underground with no pole infrastructure, which gives the next level of resilience. There is a lot of severe weather in the rural areas and B4RN’s network is unaffected unlike other providers. All our customers get a full fibre into every home from the cabinet, ready for future growth and adoption of new technologies. 

“B4RN strives to deliver the best internet service in the country to the areas that are hardest to reach. With a 400G operational Juniper network, we can bring the benefits of digital connectivity to rural communities for generations to come.”

Our partners

B4RN worked with Kubus, an IT Solutions provider, who have longstanding relationships with world-leading tech providers. They supported B4RN by providing access to cutting-edge technology at cost-effective prices, advising and identifying the technology we needed.

“We worked closely with B4RN to help evaluate the leading routing vendors on the market, and Juniper offered the most scalable solution at the best cost with the best technology,” says Alex Hammond, client director at Kubus.

The Juniper MX304 Universal Router future-proofs B4RN’s core network, delivering high performance, efficiency and resilience to allow B4RN to serve more rural communities. The MX304 router offers massive scale and efficiency in a two-rack-unit form factor that’s ideal for space and power-constrained environments. B4RN has deployed a 400Gbps core network today, with an investment-protected path to rolling out 800G in the future.

“The Juniper router is powerful but fits into a regional utility cabinet, so we can bring really fast internet to our rural communities,” says Tom Rigg.

B4RN had previously worked with Juniper Networks – it is Juniper hardware that has been running B4RN’s core network since we put the first spades in the ground over a decade ago. 

Tom Rigg continues “By connecting the backbone in a ring formation, so that every core device has a North/South (or East/West) path back to the main datacentres, including the datacentres themselves, we will gain a greater level of resilience and redundancy. This will allow hard down circuit events to happen, to get repaired and resolved, with next to zero customer impact. It will also allow for maintenance, repair and upgrades to happen on any network segment without loss of service to our customers. We can also then onboard B2B customers who wish to take advantage of the high capacity, highly available and low latency core with confidence that their service has a level of physical resilience for service loss protection.”

Partnerships such as these with Juniper and Kubus, who are both industry-leading vendors and suppliers, world-renowned for high quality, high availability, low latency equipment and networks.

In seven years’ time the traffic growth trends on networks and the additional customers that B4RN will add, we will need that capacity. So we’ve invested in it now.

In recognition of this achievement, the partnership have funded a short film, not just about the delivery of the HALO project, but also capturing the real heart of B4RN, how they build, the incredible volunteers and the wider B4RN community.
