Internet Access

The peak use periods for internet use on board tend to be first thing in the morning or when large numbers of guests return from shore excursions. During these periods, congestion can make internet access slower, just as it would on land. It is therefore best to avoid these periods if possible.

Your internet data needs to travel vast distances between the ship’s antennae and the nearest satellite, and it needs an unobstructed line of sight between them. A number of things may interfere with this, like storms and large objects that can block the signal, such as steep mountains close to the ship or tall buildings [...]

When at sea, it is not possible to access the internet using a high-speed broadband connection as you would on land. Instead, internet connectivity on board is provided by links between the ship and communications satellites in orbit far above the Earth.
