Three data centers will protect the four critical network systems which may otherwise be compromised in a major earthquake. These data hubs will contain the redundancy and data required to operate the electricity network recovery response from three alternative sites.

 These three data centres will also help to:

• Reduce risk and improve staff safety should a key site be unreachable or unsafe in emergency conditions
• Ensure critical network systems are accessible should telecommunications links fail
• Provide ready-access to critical information including plans, specifications and manufacturers records.
