    Latest Telstra Update: As we shared last night, we identified a subsequent issue affecting some calls, including to Triple Zero. The nature of this issue only became apparent as we resolved the original outage. In these cases, some people calling Triple Zero received an error message, and their phone would then try to connect to an alternative mobile network. This was a consequence of the same software defect behind yesterday’s outage. While the original issue was addressed, this one remained ongoing and needed to be fixed in a different way. Overnight, our team made good progress, significantly reducing failed calls to Triple Zero. We’ve now implemented a solution that has addressed the impact of this issue. Mobile networks are complex, and we’re continuing to work through further changes to make sure we have the most robust solution in place. Customers can feel confident calling Triple Zero.
