I'm thinking 2022 Hunga Tonga–Hunga Haʻapai eruption and tsunami "Southern Cross Cable reported that the eruption may have broken the Tonga Cable System, which connects Tonga to Southern Cross's trans-Pacific cable in Fiji.[196] Southern Cross cited a fault in the international cable 37 km (23 mi) from Nukuʻalofa, and a further fault in a domestic cable 47 km (29 mi) from Nukuʻalofa.[197] New Zealand prime minister Jacinda Ardern had earlier stated that an undersea cable serving Tonga was affected, probably due to power cuts, and authorities were urgently attempting to restore communications.[198] The chair of the Tonga Cable System, Samiuela Fonua, stated that repair crews would not be cleared to access the site of the faults before volcanic activity ceased at Hunga Tonga; with additional preparation time necessary for the repairs, internet services could be unavailable for over two weeks after the eruption."
