Telstra’s major mobile outage investigation reports that two engineers involved in a problematic system upgrade were on “mandatory standdown” when the mass service failure occurs. The outage left millions of customers without mobile services, according to the reporting.

Both outlets describe the findings as part of an investigation into what went wrong during the upgrade and how responsibilities were handled at the time the failure took place. The accounts focus on the timing of staffing status, highlighting that the engineers identified as primarily involved in the bungled upgrade were not actively working when the failure began.

While the shared reporting emphasizes the same central detail about “mandatory standdown,” the articles do not present additional differing explanations for the outage within the provided excerpts.
