London Internet Exchange Deploys 25th 400Gbps Ethernet Port
The not-for-profit London Internet Exchange (LINX), which handles a large chunk of UK and global data traffic through their switches via around 900 members (broadband, mobile, CDN providers etc.), has celebrated achieving a “major milestone” after they deployed their 25th 400GE (Gigabits per second) port across their global network.
The first 400GE port was provisioned several years ago in 2021, largely as a response to rising demand for ultra-high bandwidth connectivity, which in turn was being driven by the rapid growth in cloud services, video streaming, gaming and AI workloads.
LINX added that they’ve “invested heavily” in Nokia’s next-generation hardware optical technologies to enable 400GE delivery across its interconnection ecosystems in both London and Manchester. This investment ensures members can scale quickly and efficiently while maintaining the resilience and reliability that underpin the global internet.

Jennifer Holmes, CEO of LINX, said:
“Reaching 25 active 400GE ports is a testament to the evolving needs of our members and the strength of our technical infrastructure. We’ve seen a clear shift towards high-capacity services, with our larger delivery networks upgrading first to 400GE.
In the last 12 months UK ISPs are now seeing the demand for the service and are upgrading in London and Manchester, a positive sign of effective network traffic management or regional peering. This evolution demonstrates how network operators of all sizes are adapting to keep pace with the demands of modern digital services.”

How many years before someone steps up and offers a 400Gbps broadband service, just for the bragging rights? It’s sounds beyond insane, but they’re already doing some very early testing on 25G and 50G services in some places, so it’s not entirely inconceivable, in the 2030s! After all, just imagine telling someone a decade ago that 8Gbps broadband services would already be available now…
