But the traffic between Europe and North America still depended on satellite links: expensive, slow, and plagued by the unavoidable physics of signal delay. A round-trip to a geostationary satellite and back takes roughly 600 milliseconds. For email, that was annoying. For real-time communication, it was a wall.
