    Impact of AI on Transport | TG Explains AI

    What are the real bottlenecks in AI infrastructure development? How is this infrastructure boom similar to the 90s internet boom? How do we overcome the pricing paradox in telecom transport where demand keeps rising and service prices keep falling? Today on TeleGeography Explains the Internet, we welcome Luis Colasante, Head of Procurement Strategy for Energy & Infrastructure at Colt Technology Services. Luis brings a perspective from the intersection of energy strategy, critical infrastructure, and capital markets. In this episode, we move beyond the "compute bubble" to discuss why physical infrastructure—from subsea cables to the power grid—has become the primary bottleneck for the AI revolution. Luis explains: The Energy-Connectivity Nexus: Why AI data centers require two to three times more power than traditional cloud facilities and how energy availability is now the ultimate gatekeeper for digital expansion. Shifting Investment Cycles: A look at the parallels (and differences) between the late-90s telecom bubble and today’s hyperscaler-led boom. Digital Sovereignty: Why governments are treating subsea cables as strategic national security assets, highlighted by the French government’s recent move with ASN. The Death of the "Toll" Model: Why selling raw bandwidth has become a deflationary commodity business and how the industry is pivoting toward intelligent service layers and "Network as a Service" 2.0.

    AI Adoption in Networking | TG Explains AI

    Host Greg Bryan welcomes Jason Gintert back to the show. As the incoming President of the U.S. Networking User Association, Jason dives into the current state of AIOps in network management. This includes: Low Adoption and Key Challenges: Despite being a popular topic, AIOps adoption remains low due to concerns about trusting AI output (hallucinations) and the indeterminate nature of large language models. Data Integration and Security: The importance of integrating private data using methods like the model context protocol to make AI answers more deterministic. For security, Jason strongly recommends starting with a read-only, zero-trust mindset when exposing data to AI tools. Practical Use Cases: AI is most valuable for root cause analysis of common network problems (e.g., Wi-Fi authentication issues, circuit errors) and providing automated network summaries or predictive analysis. The Human Element: AI is seen as a powerful tool to increase the productivity of network engineers by handling low-level tasks, but it will not replace humans. Engineers remain crucial for exercising judgment and taking responsibility for service-impacting changes.

    The Impact of AI on the Network | TG Explains AI

    Our latest pod series on all things AI continues with Seva Vayner, Product Director for Cloud Edge & AI at Gcore. Seva joins host Greg Bryan to tackle what is perhaps the dominant topic in telecom today: the impact of AI on the network. The pair distinguish between "AI for networking" and "networking for AI," and explore how AI training models are driving a dramatic increase in power consumption within data centers, with rack power capacity rapidly growing over the past few years. Seva explains how AI inferencing is creating a need for distributed network infrastructure, transforming the role of Content Delivery Networks (CDNs) from simply distributing content to enabling real-time interaction with AI models. He shares how Gcore is helping telcos and enterprises adopt AI solutions and exactly what that entails. We close out on the evolving definition of the "edge" as power becomes a bigger constraint than connectivity in facilitating AI workloads and what Seva sees for the near future of AI and networks.

    All About AIOps | TG Explains AI

    It's a new year and the TeleGeography Explains the Internet team is kicking off a multi-episode series all about AI and its impact on global networks. To start, we're joined by Chalan Aras, Senior Vice President at Riverbed to discuss how the rise of Artificial Intelligence is fundamentally reshaping the way we think about the WAN. In this episode, we dive into: AI for Networking vs. Networking for AI: How Riverbed balances using AI to manage IT operations (AIOps) with the physical necessity of moving massive amounts of data to "AI furnaces" (GPUs). The AI Data Tsunami: Why data is currently growing faster than infrastructure can be upgraded, and why Time is the most critical metric for AI project success. The Shift from SD-WAN to "Data Fabrics": Chalan shares a view on why SD-WAN may be fundamentally changing or even declining as the industry moves toward more dynamic, densely connected AI data fabrics centered on the cloud and data center. Unified Observability: The importance of moving away from siloed tools toward integrated platforms that can correlate data across desktops, mobile devices, and the core network to remediate issues before users even see them.

    Cloud & Data Centers: What to Know for 2026

    TeleGeography experts Jon Hjembo and Patrick Christian answer our biggest questions about recent data center and AI booms. In this final episode of our three-part pod series reviewing the year in telecom—and looking ahead to 2026—we cover: How many data center projects were we tracking in 2025? And where are they located around the world? What kind of constraints are those projects encountering, and are rumors of a bubble warranted? Did we see an increase or decrease in cloud region development? What is surprising about the geographic location of cloud development in 2025? Are CDNs still relevant in the hyperscaler dominated world? Is bandwidth demand really all that massive in the AI world?   Podcast HQ: https://www2.telegeography.com/telegeography-explains-the-internet-podcast TeleGeography Blog: https://blog.telegeography.com/ Our Research: https://www2.telegeography.com/en/our-research

    Pricing & Enterprise Networks: What to Know for 2026

    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-podcast TeleGeography Blog: https://blog.telegeography.com/ Our Research: https://www2.telegeography.com/en/our-research

    Submarine Cables & Transport Networks: What to Know for 2026

    What were the big cable headlines of this year, and what do you need to know about transport networks in 2026? To find out, we're kickstarting our three-episode review of What to Know in the New Year. Joining us for this submarine and terrestrial infrastructure review are friends of the pod Lane Burdette and Paul Brodsky. In this episode of the TeleGeography Explains the Internet podcast, these experts address: How much of a submarine cable boom was there in 2025 and will that continue into 2026? Where are new builds located around the world and why? Will all this new capacity lead to over-supply? Are fiber developers having to chase AI data centers into novel locations? How are terrestrial builds related to submarine cable bottlenecks?    Podcast HQ: https://www2.telegeography.com/telegeography-explains-the-internet-podcast TeleGeography Blog: https://blog.telegeography.com/ Our Research: https://www2.telegeography.com/en/our-research

    How Great ISPs Nail Their Net Promoter Score Surveys

    While we hear a lot about automated provisioning and NaaS, how long does it really take to get a quote for DIA service? Or more to the point, how long does it take to actually get a circuit installed? What do enterprises really think of their ISPs? In this episode of the TeleGeography Explains the Internet podcast, Dennis Thankachan, CEO and co-founder of Lightyear, addresses these questions and more. He brings a wealth of findings from Lightyear's Enterprise ISP Experience Guide and gives us a look at what's going on in the ISP market.
