“This resulted in the failure of a number of Triple Zero calls in South Australia, the Northern Territory and Western Australia,” the release by Optus reads.
Optus, the Australia telco owned by Singapore Telecommunications (Singtel), is launching investigations into the technical failure during its network upgrade which caused the death of three individuals.
The network operator conducted a network upgrade yesterday, and within this process a technical failure impacted Triple Zero calls, which is the emergency number in Australia.
