In January, the island state Tonga's Internet connection went dark for five weeks. The eruption of the Hunga Tonga-Hunga Ha'apai undersea volcano cut Tonga's only international cable, its main domestic inter-island link.
Brian Lavallée, senior director of submarine network solutions for Ciena, joins the podcast to explain why this particular severing of an undersea cable had such an impact on Tonga's network, how satellite connectivity provided a temporary backup for the island state and advancements being made in submarine network services.
"If you can have both – meaning you have a business case to either get satellite or submarine – you always go with submarine because the sheer magnitude of capacity you can run through a submarine cable is astonishing," said Lavallée. "You'll never get that capacity over a satellite network for the foreseeable future."
