A statement from the company said the service would provide Internet access when conventional networks used by the NBN and other mainstream providers experienced an outage.
Spirit has its own fibre- and wireless-based network which provides an alternative to the NBN.
“Redundancy-as-a-Service safeguards against a number of potential disasters,” said Spirit managing director Geoff Neate.
Spirit’s RaaS offering provides a back-up Internet connection through the air, avoiding the same issues that struck down the primary network.
Last financial year, more than 7800 businesses suffered faults across telecoms platforms including the Internet, that were so severe they lodged a complaint with the Telecommunications Industry Ombudsman, up 41% on the previous year.
An additional 3232 complaints were specifically regarding connections.
