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. Catch up on our other cable conversations over here: All About Cable Economics All About Cable Security All About Cable Faults + Maintenance All About Cable Routing All About Cable Sensing   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

Tony O’Sullivan, CEO of RETN, joins Greg to discuss network resiliency. They address how providers can build networks that withstand outages, whether from someone who forgot to call the utility company or an anchor dragging on the seafloor.

We welcome Mark Englund, CEO of Fibersense. Mark explains the fascinating world of Distributed Acoustic Sensing (DAS), and how this emerging technology is turning existing fiber optic cables into sentient, continuous sensors.

Greg welcomes Tim Urban, author of the blog Wait But Why and the book ”What’s Our Problem?” The pair focuses on what happens *on* the consumer internet, not just the underlying technology and business of the web.

We welcome James Porter, Cable Route Engineer at Alcatel Submarine Networks (ASN). James spends his days studying maps to route submarine cables, ensuring ease of maintenance and compliance with guidelines. He joins Greg to discuss the challenges of seabed congestion, particularly in deep-water areas where new cables must be laid at a safe distance from existing ones to ensure they can be repaired in the future.

Our guests today presented a paper at SubOptic 25 detailing their study on global submarine cable maintenance and recommendations for the industry. Mike Constable, Principal at Infra-Analytics, and Alan Mauldin, Research Director here at TeleGeography, joined the pod to discuss their review of cable faults and the readiness of the industry to fix problems over the coming years.

Ferris Adi, Chief Information Security Officer at the Trans Americas Fiber System, joins to discuss specific threats to submarine cables and how best to build resiliency against them.

To start our new series on sub cables, we couldn’t think of a better guest than Senior Research Analyst Lane Burdette, an expert (and nerd) when it comes to cables. She and host Greg Bryan discuss the economics of submarine cables.

Joining us today is FCC Commissioner Nathan Simington. Commissioner Simington has served on the Commission since late 2020. He brings a diverse background to the role, including experience with the NTIA. The Commissioner and Host Greg Bryan cover several key issues facing the FCC: 👉 Several issues surrounding spectrum allocation and use. We talk about how FWA and LEO fit in spectrum plans, CBRS, unlicensed spectrum, and, of course, a bit on spectrum auctions. 👉 BIL and broadband development and the role wireless can play in closing the digital divide. 👉 The FCC’s role in submarine cable development and the Commissioner's views on ensuring submarine cable security. 👉 The Cyber Trust Mark and the FCC’s role in securing the ever-expanding threat perimeter and the Commissioner's views on how to get OEMs invested in keeping users safe.

Greg welcomes Michael Martin, formerly a global network and security architect at McKinsey. We get his take on the industry’s state of implementation of network automation among enterprises.

Lightyear’s Dennis Thankachan joins us to chat about their State of Connectivity Report. We also get into network prices, inflation, AI, and bandwidth.

Todd Chapman, a veteran in fiber development, explains Layer 0 of the physical infrastructure underlying data transmission.

Our first guest of 2025 is Fahim Sabir, Director of Digital Solutions at Colt. Fahim joined us to clarify the often confusing world of Network as a Service.

As 2024 ends, a few TeleGeography experts joined us on the pod to review the major telecom events of the past 12 months and chat about what we might expect in 2025.

Vinay Prabhu, Director of Product Management at Graphiant, joins us to discuss the intricacies of moving data around the globe. He outlines why we should all be thinking about data in motion and what Graphiant is doing to ensure its safe passage, particularly as AI becomes more prevalent.

To truly explain the internet, sometimes we have to get into where your internet comes from. For that, our guest today is Rutger Bevaart, CEO and Co-founder of GNX.

Our guest today is Marcel Stadler, Product Manager of SD-WAN at Open Systems. Marcel joins our semi-annual conversation on the WAN landscape

Where are we building data centers? Why? What markets are primed for interconnectivity glory? Which ones are getting left in the dust? Our resident data center expert Jon Hjembo is here to explain.

Our guest today is Jamie Pugh, CTO at Globalgig. Jamie joined the show not only to ponder all things automation, but also to discuss enterprise network orchestration in the era of an increasingly complex WAN.

Michael Wynston, Director of Network & Security Architecture at Fiserv, is back on the show for the third time. And he’s here to help us better understand how AI is developing as a network management tool.
