The Singaporean telecommunications giant, Singtel, has been hit with a hefty fine of SGD1 million, equivalent to US$774,000, by local authorities over a significant voice service disruption in 2024 that negatively impacted roughly 500,000 customers.
The communications interruption also affected the public’s ability to reach customer service departments for numerous government bodies, healthcare entities, banks, corporations, and critical emergency call services, according to the Infocomm and Media Development Authority (IMDA).
Ng Tian Chong, Singtel Singapore’s CEO, has openly accepted the ruling and monetary punishment from IMDA. He admitted the severity of the interruption to the fixed voice service in the previous October, reiterating his apology for the inconvenience and disruption experienced by the affected populace.
The IMDA explained that the scale and the impact of the outage, coupled with the duration to restore the services to normal, were the critical elements taken into consideration while imposing the penalty. The regulatory body categorized the incident’s impact as “significant” and highlighted that the potential ramifications concerning public safety and security could have been very serious.
The IMDA’s examination found deficiencies in Singtel’s monitoring systems, which lacked “adequate filters” to protect the hardware from high-intensity traffic on October 8, 2024. This inadequacy caused the voice system’s firewall to malfunction and operate intermittently. Consequently, calls were dropped intermittently as traffic alternated between the malfunctioning and functioning voice systems.
Before this event, Singtel experienced another setback in September when an emergency service outage from its subsidiary, Optus, led to three fatalities in Australia. This event was succeeded by a smaller mobile outage from Singtel on November 18, where more than 1,600 disruption reports were logged.
Singtel, the largest mobile network operator in Southeast Asia, serves a massive customer base of 800 million customers worldwide.
