Tanah Merah, Singapore is a submarine cable landing point in Singapore. 4 international cable systems come ashore here, and together they reach 4 other countries across Oceania and Asia.
Tanah Merah, is a geographical region located along the south-eastern coast of the East Region of Singapore. Its 4 systems give Tanah Merah direct international reach to Australia, Christmas Island, Indonesia and Malaysia and beyond (4 countries in all), the role that justified building international cable here rather than routing through an inland neighbour.
The roster spans 6 years of build-out, from Jakarta-Bangka-Bintan-Batam-Singapore (B3JS) (2012) to SEAX-1 (2018). Documented capacity and vintage vary across the roster: Australia-Singapore Cable (ASC) (4,600 km, in service since 2018 and 40 Tbps), Jakarta-Bangka-Batam-Singapore (B2JS) (759 km and in service since 2013), Jakarta-Bangka-Bintan-Batam-Singapore (B3JS) (1,031 km and in service since 2012) and SEAX-1 (250 km and in service since 2018). Facts for every system are on its own cable page.
With 4 independent systems, Singapore has real redundancy through this point: no single cable cut isolates it from the destinations they share. The exposure is specific: the link to Oceania rests on a single cable, with no sibling landing alongside it. Because these systems share the same short stretch of coast and shore infrastructure, a localized event at the landing zone can reach far more capacity than the cable count alone suggests. GeoCables tracks each of these systems individually for exactly this reason.
GeoCables watches these systems continuously rather than describing them once. Since 2026-03-10 we have logged 122 route anomalies across 68 cable systems worldwide. 10 have touched this location's own cables; the five most recent: a 132% round-trip latency spike on SEAX-1 (2026-04-30, recovered by 2026-04-30), a 151% round-trip latency spike on Jakarta-Bangka-Batam-Singapore (B2JS) (2026-04-14, recovered by 2026-04-14), a 326% round-trip latency spike on Jakarta-Bangka-Batam-Singapore (B2JS) (2026-04-13, recovered by 2026-04-13), a 133% round-trip latency spike on Jakarta-Bangka-Batam-Singapore (B2JS) (2026-04-05, recovered by 2026-04-05) and a 345% round-trip latency spike on SEAX-1 (2026-03-30, recovered by 2026-03-30). These were latency events on the systems' wider routes, not outages at the landing itself, and they cleared on their own. This record grows as we detect more, which is the difference between a directory entry and a monitored asset.
From the GeoCables probe network, best-case round-trip time to Singapore endpoints runs about 315 ms from Sao Paulo, about 189 ms from Minsk and about 205 ms from Tbilisi. These are paths into Singapore from our own vantage points, not a global average, and they shift as operators re-route.
The largest access networks in Singapore sit behind this coastal capacity: Singtel Fibre Broadband (16.8% of users), Starhub Ltd (12.8% of users), Cloudflare, Inc. (10.8% of users) and MobileOne Ltd. Mobile/Internet Service Provider Singapore (8% of users). See the full national picture for Singapore.
In short, Tanah Merah, Singapore carries international traffic for Singapore across 4 independent cable systems reaching 4 countries on 2 continents, and GeoCables monitors each of them in real time.
