"The fact you can post a picture on สล็อตxo Facebook or video on YouTube and people can see it anywhere in the world is mind-boggling, but it takes a lot of things behind the scenes and below the ocean to make it happen," says Alan Mauldin, research director at TeleGeography.
It is easy to overlook that our access to the internet relies on thousands of miles of cable, crossing the world's oceans. They provide the plumbing for the internet - 98% of all international internet traffic travels through them.
Some connect neighbouring countries, such as the 131km (80 mile) CeltixConnect cable between Ireland and the UK. Others like the Asian-America Gateway cable, stretch for 20,000km and link continents.
The data flashes along optical fibres as thin as a strand of hair. Each cable will have several of these at its core and then further layers of protective coating to prevent damage.
According to Daniel Sousa, managing director of manufacturing operations at SubCom, one challenge is that "the entire cable systems need to be manufactured and tested as a complete system".
Cables are tested ashore before being loaded on to ships, a process which can take around two weeks, says Orange Marine's chief executive Didier Dillard.
The company operates six cable ships, with one vessel, the René Descartes, able to lay up to 6,000km of cable.
Once telecom companies would have been the main backers of such complicated and expensive projects. But now technology giants have started putting serious money into undersea cables.
TeleGeography estimates that content providers - Google, Facebook, Amazon and Microsoft - have spent over $1.5bn (£1bn) on cable construction in the last five years.
The simple reason is that they have more demand for bandwidth than anyone else, says Alan Mauldin.
