Maintenance ended

The Campus Infrastructure department, supported by specialist electrical contractors, will be carrying out statutory high‑voltage (HV) maintenance across several University substations. This essential work is required to maintain the safety, compliance, and reliability of the University’s electrical infrastructure.

Although this work is not IT‑led, it may have an impact on IT and network services in affected buildings. Power interruptions during the maintenance windows may affect equipment that supports wired (Ethernet) and wireless (Wi‑Fi) connectivity, meaning network services may be at risk while work is underway.
