What each country and landing point keeps if Indonesia Global Gateway (IGG) System goes down. A calculation from our cable and landing-point database, not a forecast.
Madura, Indonesia: no other cable lands within 50 km.
On an island this means losing the submarine link; on the mainland traffic can still go over land.
Our alerts on this cable in the last 180 days: 1, last on 5 Sep 2026. Events feed →
Counted: other international cables landing in the same country (domestic cables between points of one country are not a way out), other cables at landing points within 50 km, and whether the country has land links. Not counted: cable capacity, operator contracts and satellite. Use as a first look at dependence, not as a statement of what would happen.

About the Indonesia Global Gateway (IGG) System Cable System
Indonesia Global Gateway (IGG) System: Connecting Indonesia's Archipelago and Singapore
The Indonesia Global Gateway (IGG) System is a submarine cable network designed to enhance connectivity within Indonesia's vast archipelago and link it to Singapore, a major regional hub for international telecommunications. Spanning approximately 5300 kilometers, the cable connects multiple Indonesian cities and islands, including Bali, Jakarta, and Makassar, to Tuas in Singapore. Owned by Telin and Telkom Indonesia, the IGG System is listed as in service and was recorded as ready for service in 2018 according to GeoCables data.
What makes the IGG System particularly interesting is its role in bridging Indonesia's dispersed geography, which comprises over 17,000 islands. The cable's multiple landing points across Indonesia provide essential interconnectivity for domestic and international traffic. However, several technical specifications, such as design capacity, fiber pair count, and supplier details, remain undisclosed in public sources, leaving gaps in understanding its full technological scope.
The IGG System connects ten landing points, nine of which are located in Indonesia: Bali, Balikpapan, Batam, Dumai, Jakarta, Madura, Makassar, Manado, and Tarakan. These locations span key urban and industrial centers across the country, facilitating both domestic and international data exchange. The cable terminates in Tuas, Singapore, a critical node for global internet traffic. This route reflects the strategic importance of linking Indonesia's islands internally while providing a gateway to international networks via Singapore.
Why it was built and what it carries
The IGG System was built to address Indonesia's unique challenges in telecommunications infrastructure, given its archipelagic geography. By connecting major cities and islands, the cable supports domestic data traffic and provides redundancy for existing systems. Additionally, its connection to Singapore ensures access to international bandwidth and enhances Indonesia's position in regional telecommunications.
While specific details about the cable's data capacity and technology are not publicly disclosed, its role in supporting broadband services, cloud computing, and enterprise connectivity is evident. The cable likely carries a mix of internet, voice, and enterprise traffic, serving both domestic and international needs.
History: what can be established
The IGG System was recorded as ready for service in 2018 according to GeoCables data. No conflicting dates have been identified in industry sources, suggesting a consistent timeline for its operational launch. The cable was developed by Telin and Telkom Indonesia, two prominent players in Indonesia's telecommunications sector, to meet growing demand for reliable connectivity.
Capacity and technology
Publicly available information does not disclose the IGG System's design capacity, fiber pair count, or supplier. Without operator documentation, attributing these details would be speculative. However, given the cable's strategic importance, it likely employs advanced optical fiber technology to support high-capacity data transmission. The lack of transparency on these specifications is not uncommon in the industry, where commercial and security considerations often limit disclosure.
Latency: the physics
Theoretical calculations based on the cable's length of 5300 km suggest a one-way light propagation latency of approximately 26.0 milliseconds, with a round-trip time (RTT) floor of 52.0 milliseconds over the wet segment. Real-world latency is higher due to additional factors such as land tails, terminal equipment, and routing.
Live measurements from remote probes, which capture the full internet path rather than the cable itself, show significant variability. For example, Tuas to Manado measurements recorded a minimum latency of 6.4 ms, which is below the physical floor and identified as a measurement artifact caused by rate-limited ICMP replies from intermediate routers. Similarly, Singapore to Manado recorded a minimum latency of 19.4 ms, also below the theoretical floor. These anomalies underscore the importance of distinguishing between theoretical cable performance and real-world internet path measurements.
Redundancy: what happens if it breaks
The IGG System operates in a corridor with substantial redundancy. Alternative cables at its landing points include major systems like SeaMeWe-5, INDIGO-West, and Apricot at Tuas, as well as JaSuKa and Palapa Ring West at multiple Indonesian locations. These alternatives provide backup routes for data traffic in case of disruptions to the IGG System. Repair logistics for submarine cables typically involve specialized vessels and can take weeks depending on the fault's location and severity.
Bottom line
The IGG System spans 5300 km, connecting nine locations in Indonesia to Tuas, Singapore.
Owned by Telin and Telkom Indonesia, it was recorded as ready for service in 2018.
Design capacity, fiber pairs, and supplier details are not publicly disclosed.
Theoretical latency floor is 52.0 ms RTT over the wet segment; real-world measurements show variability due to internet path factors.
Redundancy is provided by numerous alternative cables at its landing points.
