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.
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 Lands End to John O'Groats and everywhere in between
We have over 5,000 km of optical fibre
Our backbone runs at 100Gbit/s (with an interconnect capacity of around 40Gbit/s)
The network is regarded as mission critical to the UK’s knowledge economy.
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.
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.
If you are applying for a Janet network connection, you will usually be provided with a Janet IP address range as part of the ordering process.
If you currently have a network number that belongs to a commercial ISP, it will not be possible to connect you to the Janet network using the existing range. In this instance, you will need to re-number your network.
If you have a provider independent assigned range, it should be possible to retain these addresses when connecting to the Janet network.
The network service is centrally funded for higher education organisations, further education organisations and the Research Councils.
Higher education organisations pay an annual network charge
Further education organisations pay for additional bandwidth above that already paid for by the relevant further education funding body
Organisations not funded through the central charge may purchase a Janet network connection (provided the organisation meets the eligibility policy).
Please ensure your organisation understands and adheres to the security policy.
This service provides network connectivity from an organisation to the Janet network and so to the Janet community and to the rest of the world.

The external network connections to the global internet use multiple locations and multiple suppliers for resilience.
The organisation's connection to the Janet network will only be resilient if the organisation has purchased a second connection from Jisc or, in some circumstances, from a commercial ISP.
Additional connections to the Janet network, either for resilience purposes, or for multi-site organisations, may be purchased. Please contact the service desk for more information.
