IC5 cost $17 million and is adjacent to IC4, providing additional capacity for Government cloud workloads and an additional secure facility to back up data.
This expands Macquarie's sovereign data centre capacity in Canberra to 4MW.
IC5 is a Tier IV, SCEC Zone 5 ready data centre, supported by over 150 NV1 government-cleared engineers.
The new data centre features a five-ton solar rooftop installation and a power usage effectiveness (PUE) ratio of 1.35.
The official launch follows the on-time and on-budget completion of IC5 in December 2020, despite COVID-19 restrictions and record rainfall in October.
"Data and cloud demand has skyrocketed as the pandemic continues to bring forward years' worth of IT and digital transformation projects," said Macquarie Data Centres group executive David Hirst.
"Ensuring that data remains secure, sovereign and within Australia's borders is vital to protecting our national security and privacy interests – this facility embodies that need in every way."
Macquarie Government managing director Aidan Tudehope said "Government agencies cannot risk having all their data eggs in one basket.
"Canberra needs greater diversity in its balance of data storage, protection and management, and the Australian Government wants greater competition in the local market that supports government agencies. IC5 is not just welcome, but necessary infrastructure for government agencies that are increasing their cloud and IT needs."
