Here’s an article from The Economist today about large tech companies running their own fiber to reduce network congestion and costs. Very relevant to this course and is fairly accessible for students. I am assigning it as a short homework assignment along with a couple discussion questions.
@dougmmcnally thanks for bringing it up. I work for one of the companies mentioned. There is long term investment in this area with use of data, cloud continue to grow. Here is a map of under-sea cables. On the other hand there is this need for privacy and security that the recent Equifax ( it seems back to back twice ) breach reminds us is so important. Europe leads in privacy control and GDPR is going to be important step which probably the whole world will follow.
