What Happened When a Pacific Island Was Cut Off From the Internet

The Hunga Tonga-Hunga Ha'apai volcano erupted on January 15, 2022. The pyroclastic flow severed both of Tonga's underwater internet cables. The eruption cut sixty-five miles from the domestic cable and fifty-five miles from the international link to Fiji. Tonga lost all internet access. The cables sit on the ocean floor and carry 95% of the world's international internet traffic. The Guardian has a long read on what happened in the aftermath. A.T.M.s (cash machines) stopped working because banks could not verify account balances. Businesses could not file export paperwork. Foreign remittances made up 44% of the country's G.D.P. The government found old satellite phones. Three or four days later, officials restored a hundred and twenty megabytes per second of bandwidth for essential work. A month after the eruption, SpaceX donated fifty Starlink terminals. SubCom's repair ship Reliance took five weeks to restore the international cable. Vava'u did not get broadband back until August, 2023. Another earthquake in the summer of 2024 severed the domestic cable again.
