Serving over 18 million users, the Janet Network provides UK research and education with a highly reliable and secure world-class network, enabling national and international communication and collaboration.
About the Janet Network
Janet is a high-speed network for the UK research and education community.
A Janet Network connection gives you an extremely reliable and high bandwidth network that will support innovation, research and learning at your organisation and may also provide you with access to other Jisc services at no additional charge.
Did you know?
- Our network covers the UK from Cornwall to the Shetlands and Belfast to East Anglia
- It’s the busiest National Research and Education Network (NREN) in Europe, carrying over 1.5 PBytes of information annually
- At its heart lies over 8,500 km of optical fibre carrying multiple 400 Gbit/s backbone circuits
- Over 700 Jisc members are connected via more than 30,000 km of access circuits
- We have a total of over 1.5 Tbit/s of connectivity to hundreds of global networks, cloud services, content providers and more
It’s easy to see why the Janet Network is regarded as mission-critical to the UK knowledge economy.

Foundation DDoS mitigation service
The foundation DDoS mitigation service is automatically provided to all Janet-connected institutions.
Our security analysts carefully monitor the patterns of traffic across the Janet Network. If a Janet-connected institution experiences a DDoS attack, traffic patterns trigger alerts and an active response from security analysts.
Research and education organisations in the UK can connect their network to the Janet Network if they are:
- Government funded further and higher education organisations
- Research Council led organisations
- An organisation whose main activity is in higher or further education or who is involved in collaboration with the research or education community (in the UK or elsewhere).
Organisations that wish to connect to the Janet Network are bound by our policies.
If you are interested in connecting to the Janet Network, please email the connections management group or call 01235 822308.
The majority of organisations that connect to the Janet Network have a primary connection. A primary connection provides access to the Janet Network, the internet and a range of services, all underpinned by the Janet Network SLA.
If you want to connect another campus to the Janet Network or improve resilience by installing a second connection at a separate location, we can provide you with details of the options available and a quote for the charges that apply. These additional connections provide you with the same benefits as a primary connection to Janet.
We can also offer backup connection arrangements, depending on whether the service needs to always carry traffic or not. The level of costs charged and the technical implications will vary according to your requirements.
You can find more information on different types of connections and other related information on our community site.
For more information about any of these connections and charges that may apply, email the connections management group or call 01235 822308.
The terms for the provision of the Janet Network service apply to the provision of a connection to the Janet Network. They define the services provided by us, the responsibilities placed upon an organisation receiving these services, and any charges that may be made for these services.

We operate an open peering policy and all ISPs are invited to peer. We are present at the LINX, IXLeeds and IXManchester.
If and to the extent JSL agrees to permit the exchange of data traffic between our respective networks (“Peering”), and on the basis that this Peering is provided without charge, this Peering is made available without warranties of any kind, whether express or implied.
The Peering is provided “as is” and “as available” and is used by you at your own risk. JSL will not be liable for damages of any kind in respect of your use of our network, including, but not limited to, direct, indirect, special or consequential damages, to the fullest extent permitted by applicable law
In addition, if there is significant benefit through the provision of services or through the level of traffic, we can set up private peerings at suitable external peering points.
You can also join in the discussions with the Janet Network peering policy group on our community site.
This service is included within the scope of our ISO9001 certificate.
