Notice of major IT infrastructure work
Widespread disruption to services whilst we upgrade the firewalls
We're building the foundations for better IT, beginning with the upgrade of our site firewalls. This is a major piece of our network infrastructure and these works will cause a brief but widespread outage to all internet and cloud based University services which are protected by these firewalls.
In order to minimise the disruption as much as possible, we are proposing to do the work outside core office hours and during one of our agreed maintenance windows. The majority of the work will be done throughout the early hours of Tuesday, 17 December, between 3.30am and 5.30am. During these hours, there will be short but widespread outage to the majority of University services. Once the network is restored we will test all affected services to check everything is working, and aim to have completed these tests by 8.00am.
Why are we carrying out this work now?
The firewalls are the single most critical component in the provision of connectivity between the University and the internet including all our external sites as well as access to all our cloud based services.
The software platform of our existing firewalls is no longer supported, which means no more security fixes will be released for them. Unless we replace our firewalls, this will present a significant risk to the University in terms of capability and security vulnerability.
What are the benefits of replacing the firewalls?
Our supplier (Fortinet) is an industry leader for next generation firewalls. Our new platform will provide students and staff with a faster, more responsive service which will enable us to take advantage of increased internet speeds and capabilities.
Upgrading the firewalls will provide us with a resillient platform that will greatly enhance our security capabilities over the next 5 years providing students and staff with peace of mind.
Which services will be affected?
All University services which rely on internet connectivity via our network will be unavailable for a short time whilst the work is carried out. This will include any cloud hosted services which are accessed off campus and require a University login.
