The subsea cable providing Tonga, a country in the South Pacific Ocean, with broadband, the Tonga Cable, has been out since 20:30 local time on Sunday night, with the nation now relying on satellite internet instead.

Tonga Cable Director, Paula Piveni Piukala, said Kacific is working to boost internet and voice capacity for priority communications. "We appreciate Kacific's assistance, as Tonga currently has no other internet or mobile phone connectivity to the outside world," Piukala said. "Kacific's satellite service ensures that essential services can be maintained as we work to resolve the issue."
