TelkomGroup Speeds Up Service Restoration After NTT Earthquake

PT Telkom Indonesia (Persero) Tbk, known as TelkomGroup, is rapidly working to restore telecommunication and digital services in the Nusa Tenggara Timur (NTT) region after a significant earthquake struck on August 15, 2026. The natural disaster disrupted several of TelkomGroup's telecommunication infrastructures, leading to a decline in the quality of mobile, fixed broadband, and other digital services in affected areas.

Prioritizing personnel safety, TelkomGroup mobilized technical resources and optimized backup power systems to maintain community connectivity during the emergency. Telkom's President Director, Dian Siswarini, reported that network traffic is gradually normalizing. Initially, about 50% of Telkomsel's base transceiver stations (BTS) were affected, but swift repair efforts and the restoration of electricity have led to a substantial recovery.

"Alhamdulillah, traffic is gradually normalizing, although initially around 50% of Telkomsel's BTS were disrupted, but currently, in line with our acceleration of repair efforts and the returning electricity, most have been restored. Telkom is committed to performing repairs quickly, safely, and in a coordinated manner while strengthening network resilience through backup," Siswarini stated during a coordination meeting on earthquake response in NTT on August 16, 2026.

Currently, 85% of Telkomsel's total 735 BTS sites are operational, with the remaining sites still undergoing repair. Restoration efforts are focused on priority areas including Nagekeo, East Manggarai, Manggarai, West Manggarai, Alor, Ende, and Ngada, considering field conditions and supporting infrastructure readiness. This rapid progress saw approximately 400 BTS and 2,600 IndiHome (fixed broadband) customers impacted by the initial quake restored within 24 hours.

Overall, 98.3% of IndiHome's 17,062 customers are now being served, with ongoing efforts to restore service for the rest. The main backbone network remains functional due to backup lines. However, damage to some land and undersea fiber optic cables has reduced service capacity in certain locations. To expedite the recovery, 300 TelkomGroup technical teams are actively working in the affected regions, conducting assessments, network restoration, and infrastructure repairs in coordination with relevant parties. They are also maximizing the use of mobile and fixed generators to ensure continuous power supply.
