The Engineering Challenges of AI: From floor loading for 6,000-pound racks to the transition from air to liquid cooling, Phill explains the "fungible" design needed for modern AI factories. The Infrastructure Bottleneck: Why AI is ultimately a network-dependent technology and how high-speed optical networking between buildings is pushing against the limits of physics. Sustainability and Power: How the industry is chasing power availability and pioneering new ways to build modular, carbon-traceable infrastructure.

  Pricing & Enterprise Networks: What to Know for 2026 18.12.2025 47min

  Welcome to the second episode in our three-part series catching up on the most interesting stories in telecom from 2025, and looking forward to what we expect in 2026.  Today's episode focuses on all things pricing and enterprise networks. We're joined by Rob Schult, who leads TeleGeography's pricing practice, and Brianna Boudreau, who manages our SD-WAN and NaaS research. These experts tackle questions like: Are we really seeing the most rare phenomenon – telecom pricing stability? What role is AI playing in this? Just how big are some backbone connections and how do those prices relate to lower sized circuits? Has SD-WAN become the norm in the enterprise networks world? Which SD-WAN players are left? Is SD-WAN mostly about security now?   Podcast HQ: https://www2.telegeography.com/telegeography-explains-the-internet-podcastTeleGeography Blog: https://blog.telegeography.com/Our Research: https://www2.telegeography.com/en/our-research

  Space Weather + Sub Cables | Shibaji Chakraborty, PhD 16.10.2025 32min

  Perhaps you've seen the Aurora Borealis. This is a beautiful example of what we call space weather. But did you know that space weather could take out service on submarine cables? Shibaji Chakraborty, a research scientist at Embry-Riddle Aeronautical University, joins the show to explain how space weather can affect the critical, metallic power-feed cables that run alongside the fiber-optic lines to power repeaters on the ocean floor.  Shibaji shares historical examples and discusses the ongoing research and industry collaboration needed to better understand, model, and mitigate these risks. We're adding this special bonus discussion to our submarine cable pod series.
