A Volcanic Eruption Cut Tonga's Only Undersea Cable Connection

Cable faults happen fairly often and for a variety of reasons.

Most of the time, damage to submarine cables comes from human activity—primarily fishing and anchoring. But environmental factors can also cause a cable to break. 

This just happened in Tonga, where an underwater volcanic eruption and subsequent tsunami damaged the country's only undersea cable. Early reports indicate that it could be a few weeks before the necessary repairs are made. More on that below.

The Mystery of International Bandwidth Demand

Over the last decade, there has been substantial growth in demand for international bandwidth on major subsea cable routes.

In response to this rapid pace of demand growth (our research implies that demand is more than doubling every two years), there are over $2 billion of new cables entering service this year alone.

In short, demand is going up and we're seeing new cables.

This all makes sense.

But who is actually using this capacity? And will international demand continue to grow so expeditiously?
