What happened
A cyber attack on the C2K network disrupted access to digital tools used by schools across Northern Ireland at a critical point ahead of exam season. The attack shut down the network, cutting off students from online learning platforms, email communication, and key resources such as OneDrive that they rely on for revision and coursework. The disruption occurred in early April 2026, just weeks before exams were due to begin. The Education Authority said it is working with the Information Commissioner’s Office and other relevant authorities to investigate the incident and restore access. The outage has left students without core digital services used for exam preparation and day-to-day schoolwork during a high-pressure period.
Who is affected
The direct impact falls on students and schools across Northern Ireland that rely on the C2K network for online learning, email, and access to revision and coursework materials. The disruption is especially significant for students preparing for exams, as the network serves as a central part of the region’s digital education environment.
Why CISOs should care
This incident matters because it shows how disruption to a shared education platform can immediately affect student readiness, communication, and access to core academic resources. It also highlights the operational dependency that schools now have on centralized digital infrastructure during critical academic periods.
3 practical actions
- Build exam-period continuity plans: Ensure schools can continue revision, coursework access, and core communications during outages affecting central education platforms.
- Identify critical student-facing dependencies: Map which services, such as email, cloud storage, and learning platforms, create the greatest disruption when they become unavailable.
- Coordinate restoration with regulators early: Align incident response with education authorities and data protection bodies quickly when an attack disrupts systems used across multiple schools.
