TeleGeography Explains the Internet

Greg Bryan sits down with Dennis Thankachan, CEO and Co-Founder of Lightyear, to explore how agentic AI is transforming the notoriously painful processes of telecom sourcing, provisioning, and lifecycle management.

The show welcomes Carlie Carson, Research Analyst on the enterprise team at TeleGeography. Carlie and Greg discuss the shifting underlay landscape as MPLS usage drops and DIA takes center stage, why enterprises choose DIA over business broadband, and the real impact (or lack thereof) that AI is having on current enterprise bandwidth demands.

A trio of TeleGeography experts close out our series on the impacts of AI on global telecom. Host Greg Bryan sits down with Alan Mauldin, Patrick Christian, and Jon Hjembo to tie together the network, cloud, and data center layers of this infrastructure puzzle.

The TeleGeography Explains the Internet podcast welcomes Jezzibell Gilmore, General Manager, Service Provider at Kentik. She discusses the profound impact of artificial intelligence on global network infrastructure, and how networks are evolving to handle new technological demands.

Host Greg Bryan welcomes Phill Lawson-Shanks, Chief Innovation Officer at Aligned Data Centers. With several decades of experience in digital infrastructure, Phill has seen the industry evolve from mainframes and green screens to the massive hyperscale cloud platforms we rely on today. In this episode, we explore: The Shift in Data Center Geography: Why the "center of gravity" for networks is moving toward new power-rich zones and how the rise of AI is rewriting the rules of connectivity. 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.
