Telstra (TLS) Major Outage Affects Train Services and Emergency Calls

Telstra (TLS) experienced a major outage starting at 04:30 local time on Wednesday, impacting mobile coverage for thousands and disrupting train services. The outage lasted approximately 12 hours and was caused by software defects in time-keeping servers, not a cyber attack. The disruption affected emergency calls, leading to welfare checks for customers who could not reach services. This incident matters as it raises concerns about the reliability of Australia's largest telecom network, with potential implications for customer trust and regulatory scrutiny.
