The UK’s journey toward a quantum-enabled future has taken an important step forward with Jisc becoming a member of UKQuantum. This strategic move establishes a practical foundation for collaboration between academia, industry, and government to help realise the UK’s ambition of building a secure and scalable quantum network by 2035. At the heart of this […]
A resilient, high‑capacity global network of NRENs (National Research and Education Networks) is one of the most quietly powerful forces behind modern science. It’s the digital backbone that lets researchers in Oxford collaborate with teams in Tokyo, Cape Town, or São Paulo as if they were in the same building. Without it, many of today’s […]
In an era where digital infrastructure underpins almost every aspect of national life, the concept of sovereignty can no longer be confined to borders, flags, and armed forces. It now extends deep into the digital realm — into data, platforms, and crucially, networks. For the UK, one of the most quietly powerful examples of network […]
For the UK, artificial intelligence is central to long‑term economic growth, national resilience, and public‑service reform. Through multi‑billion‑pound investments in AI research, supercomputing, and digital infrastructure, the UK government is backing AI not as a speculative technology, but as a core national capability. What is increasingly evident, however, is that these AI ambitions rise or […]
Every few years, satellite connectivity re‑enters the spotlight with headlines promising the end of terrestrial networks. Low Earth orbit (LEO) constellations and reusable rockets have fuelled claims that satellites could one day replace fibre entirely. This article examines whether that’s feasible. While satellite technology has improved dramatically, the idea that it could replace fibre‑based ground […]
In an era where connectivity is often treated as a commodity, it’s easy to assume that all network connections are broadly the same. But for the UK’s education, research, and public sectors, a connection to Janet represents something fundamentally different—and increasingly important. Janet is not designed to compete with commercial internet providers, or to serve […]
This month, Jisc has reengineered connectivity between Janet and GÉANT, now delivered via a single 400Gbit/s port (previously multiples of 100Gbit/s) — a significant step that reinforces the UK’s place at the heart of global research and education.As well as the obvious benefits of lower port, power and space consumption, this upgrade reflects the growing […]
By Neil Shewry and Rob Evans On the 1st of April, whilst many are playing pranks on each other, we at Jisc are reflecting on the anniversary of the Janet Network, the National Research and Education Network (NREN), that has quietly powered innovation, collaboration, and discovery for generations. For those of you who may not […]
Aim of the Article This article is a two parter looking at how Jisc is using RPKI to protect its customers. This first episode describes how we are protecting customers by dropping potentially malicious or incorrect routes at our boundary so that customer traffic is not black-holed or routed to potentially harmful resources. Part two […]
A common question that comes up when our Jisc network performance team talks with researchers and other people at Janet-connected sites is whether it’s realistic to expect to be able to move a certain amount of data over the network in a certain period of time. What are reasonable expectations? You can come at this […]
