Steve McCracken: Secondary Principals' Council Chair on Hillmorton High School closing for two days after rats chewed through a fibre cable

Questions have been raised over how a single fibre cable, chewed through by rats, was enough to shut down an entire Christchurch secondary school. 

Hillmorton High School has reopened today after asking students to learn from home for two days because of the damage. 

The school lost WiFi, phone lines, CCTV, and access to the student management system. 

Secondary Principals' Council Chair Steve McCracken told Mike Hosking while the circumstances are bizarre, schools can't operate safely when critical systems go down.
