This map is interesting too: https://www.us.ntt.net/about/network-map.cfm https://www.us.ntt.net/about/network-map.cfm It shows some overland links as well but it doesn't show intermediate hops. For example, you can see from other maps that most Pacific cables stop off in Hawaii. You can match the nodes to entries in a trace root log. I did this for a chapter (on network latency and performance) in my last book.
