Historical outages data

Major outage
A major outage is when there is an unplanned adverse impact to a telco network supplying carriage services to end-users which:

• results in an end-user being unable to establish and maintain a carriage service and
• affects, or is likely to affect:
  • 100,000 or more services in operation; or
  • all carriage services supplied using the network in a state or territory; and
• is expected to be, or is, longer than 60 minutes.

Significant local outage
A significant local outage is when there is an unplanned adverse impact to a telco network supplying carriage services to end-users, which: 

• results in an end-user being unable to establish and maintain a relevant carriage service; and
• is not a major outage; and
• affects or is likely to affect:
  • 250 or more services in operation in remote Australia that is expected to last for 3 or more hours
  • 1,000 or more services in operation in regional Australia that is expected to last for 6 or more hours.

Why are significant local outages in metro areas not included?
When outages affect Australian major cities, the overlap of all the networks usually means end-users will stay connected. At a minimum, they can make emergency calls from a mobile.
