Welcome to Micron21

Australia's First Tier IV Data Centre

We're a Tier IV data centre at our core, but we're also much more. Whether you're a small business, an enterprise or a government body, we can help by providing an array of fully tailored services for all your cloud, network, cybersecurity and support needs.

We've also been behind significant Australian firsts:

  • Becoming Australia's first Tier IV data centre
  • Building Australia’s own global DDoS protection platform
  • Creating a next-generation Australian cloud platform, called mCloud, which provides flexibility, high-availability, and enterprise grade scalability at a fraction of the cost of the hyper-scalers
  • Created the third largest peered network in Australia - well ahead of the telco giants - ensuring low latency and network resiliancy for all Micron21 services
