The Brief

  • Indonesian official Hafid warns 80% of Singapore’s internet could be affected if undersea cables are cut.
  • Singapore’s former parliamentarian suggested cutting cables, though he later clarified it was not a serious proposal.
  • At least 24 submarine cable systems connect Singapore and Indonesia, with 17 currently operational.

Singapore’s former parliamentarian Calvin Cheng previously suggested cutting submarine fiber-optic cables, though he later stated the idea was not serious.

Hafid, an Indonesian official, warned that if the cables are cut, either intentionally or unintentionally, 80% of Singapore’s internet connectivity could be disrupted.

Hafid also highlighted Indonesia’s digital market, noting 267 million internet users have attracted global tech investment to the region.

Without this user base, Hafid suggested investors from global technology firms might reconsider their presence in Singapore.

Singapore and Indonesia are connected by a network of submarine cables that carry internet traffic between Southeast Asia and the rest of the world.

According to TeleGeography data cited by Katadata, at least 24 submarine cable systems link the two countries, with 17 currently operational and seven planned.
