I have written about the TeleGeography telecom maps before, but I think they deserve a repost this year for their 2015 Submarine Cable Map. It is a beautiful Mercator / old-style map with a lot of information, and some fun elements like the sea creatures. Their maps are realeased with a creative commons attribution and can be downloaded in a big size or viewed online as an interactive map. All their maps can be found on their map gallery page, where they also have a Middle East Telecommunications map for 2015, and other maps in different styles dating back to 1999.
