Chile’s Subtel orders telecoms to harden networks

Chile’s telecommunications undersecretariat, Subtel, has ordered telecom companies to strengthen network continuity after Senapred reported a frontal weather system. The directive calls for permanent monitoring, 24/7 supervision of trunk routes, reporting of significant outages and preparation of emergency response mechanisms. The available background does not point to a cybersecurity incident or any specific cyber threat linked to this case.

What did Subtel ask companies to do?

Subtel required continuous network monitoring and ongoing oversight of trunk routes, including national, aerial and submarine fiber optic links. It also ordered companies to report significant outages through its Emergency Management System, according to the communication released by the undersecretariat itself.

The measure is aimed at keeping connectivity up during a meteorological emergency. In that context, the authority said operators must keep their response mechanisms ready for possible service disruptions.

What contingency measures were activated?

The contingency plan includes preserving the Emergency Alert System and keeping the National Emergency Automatic Roaming service available. CNN Chile also reported that critical Level 1 sites must have up to 48 hours of electrical autonomy, while Level 2 sites must have at least four hours.

The deployment of mobile emergency vehicles is also part of the scheme. According to El Morrocotudo, they can be sent at Senapred’s request and in coordination with Subtel when an outage affects communications in an area.

What electrical context accompanied the measure?

Senapred reported that the frontal system left 14,000 customers without power, a situation that can affect the continuity of telecom nodes and networks. That figure helps explain why the authority tightened requirements for operators.

The available information does not describe an attack, malware incident or confirmed ICS or OT impact. The verified fact is the rollout of preventive continuity and emergency response measures tied to severe weather in Chile.
