Telstra releases findings from July mobile network outage
- An independent investigation confirmed a technical error triggered a Telstra outage impacting Triple Zero emergency calls.
- Auditors found the company failed to classify its network timing system as a critical capability requiring peak oversight.
- The telecommunications provider stated that implementing necessary fixes will not alter its FY27 financial projections.
Telstra (ASX:TLS) has released an independent investigation into a July 8 mobile outage that disrupted emergency Triple Zero calls for Australian users.
The review confirmed that planned maintenance caused incorrect date data to spread across parts of the mobile network, matching initial reports from the business.
“It was an outage that should not have happened. In the days after the outage, I committed to being transparent about what happened, what we’d learn from it, and what we’d do differently,” said Telstra CEO Vicki Brady.
External auditor Technology Audit Partners reported that operational support gaps and a lack of system visibility delayed early identification of the failure.
The company submitted these technical findings to a Senate enquiry and confirmed the incident remains subject to an Australian Communications and Media Authority investigation.
Following the announcement, the Telstra share price was unchanged at $4.63.
The findings highlighted that the network timing system lacked the highest levels of operational protection prior to the failure.
Telstra stated that the remedial actions required to implement the audit's recommendations are not expected to impact its FY27 guidance.
