The problem
St Columba College is a large Foundation to Year 12 school located in Adelaide's northern suburbs, operating across multiple campuses in Andrews Farm.
With a large student population and increasing reliance on digital learning platforms, the college required high-performance, reliable infrastructure to support teaching, administration, and communications across all campuses.
Operating across multiple sites introduced challenges around connectivity, performance, and maintaining consistent access to systems. The school also required a modern, scalable platform to support growing demand for internet-based services, cloud systems, and high-volume communications.
What we did
Caznet delivered a complete infrastructure, connectivity, and communications platform across all campuses.
Core systems were deployed into a secure data centre environment using a combination of co-location and private cloud services, providing a resilient and scalable foundation for the college's IT environment.
Each campus was connected via dedicated 10 Gbps fibre links, creating a high-speed network between sites and the data centre.
A multi-gigabit internet service was deployed to support the large number of users and high demand for online services, with a backup NBN connection providing redundancy.
Caznet also implemented a unified business phone system supporting approximately 180 handsets across the college, enabling consistent and reliable communication across all campuses.
The result
St Columba College now operates on a high-capacity, enterprise-grade network with 10 Gbps connectivity between campuses and its centralised infrastructure.
The platform supports modern digital learning environments, high-speed access to cloud services, and reliable communications across the entire college.
The combination of private cloud, data centre infrastructure, and redundant connectivity provides a resilient environment capable of supporting the college's ongoing growth and increasing technology demands.
With a scalable and high-performance foundation in place, the college is well positioned to support both current operations and future expansion.
"Caznet has provided exemplary specialist support to St Columba College for over a decade. All projects have been completed on time, within budget and always well communicated throughout."
