Cirrus Communications

Cirrus Communications, also known by its alias, is a fixed wireless telecommunications provider headquartered in Australia. The company delivers broadband connectivity to a range of customers that includes business enterprises, residential complexes, and military installations. Its service relies on radio‑based links to provide internet access without the need for physical copper or fiber cables. By concentrating on the fixed wireless segment, Cirrus Communications addresses markets where traditional wired infrastructure may be limited or costly to deploy. The organisation’s core offering is centred on maintaining and operating the radio network that links customer premises to its backbone.

A distinguishing characteristic of Cirrus Communications is its focus on the core network infrastructure rather than the edge radio equipment that directly connects end‑users. This emphasis on the core was highlighted during a distributed denial‑of‑service incident on 29 July 2014. The attack overwhelmed the company’s central infrastructure, disabling more than half of its network and causing extended service disruptions for its customers. Despite the scale of the outage, near‑full restoration was achieved shortly after the event, with only minimal residual outages reported. The origin of the attack remained unidentified at the time of reporting, underscoring the challenges associated with defending large‑scale core network assets. Serving military bases and other critical‑facility customers further sets the provider apart as a trusted partner for secure and reliable communications. These attributes collectively define Cirrus Communications’ niche within the Australian fixed wireless landscape.
