The outage affecting about 1.5 million Australians on the Oasis service is a “significant loss” and will affect about 700,000 people, according to a telecommunications provider.
Oasis said it was “shocked and saddened” to learn of the outage.
It said it had been working with the Australian Competition and Consumer Commission to assist with the outage but it would not disclose the extent of the losses until it received more information.
Oasis said in a statement that it was working to make sure customers have access to services as soon as possible.
The outage has caused delays for many people, including some in rural areas, but also affected businesses and hospitals.
According to Oasis, the outage occurred on March 24 when it received a complaint about a problem with the service, which Oasis says has not been fixed.
The company said it has worked with the customer and the service has been restored.
While the service remains offline, customers can still access the Oases website and search for services.
Oases said the outage affected some Oasis customers who were in remote areas and some customers who had not signed up for Oasis broadband.
Oasis was established in 2010 by former Australian Communications and Media Authority chairman Peter White.
