Telemetry Now

Doug Madory joins us to unpack the recent Red Sea submarine cable cuts and how Kentik’s Cloud Latency Map revealed the global impact in real-time, offering critical insight into cloud performance, interconnectivity, and internet resilience.

Lauren Basile joins us to show how traffic-aware cost intelligence turns spreadsheet guesswork into one-click, per-slice cost estimates across customers, ASNs, and CDNs. Learn about the SNMP plus contracts foundation, the flow-data leap, and how NetOps teams use cost-per-Mbps and path insights to optimize spend, pricing, and margins.

AI training isn’t just about GPUs, it’s about the network that ties them together. Host Phil Gervasi sits down with Vijay Vusirikala to unpack why job completion time is the true metric of success, how optical interconnects shape AI data center performance, and why power efficiency and observability are becoming mission-critical.

In this episode of Telemetry Now, Phil and guest David Cliffe explore “neocloud”—what it is, why it’s growing fast, and how it’s reshaping AI infrastructure. From GPUs and high-speed interconnects to orchestration layers and energy constraints, we discuss what makes neocloud different from traditional cloud, and what it means for data center operators, service providers, and AI architects.

In this Telemetry News Now episode, Phil Gervasi and Justin Ryburn tackle Intel’s plan to spin off its Network & Edge Group (NEX) and what it means for high‑performance Ethernet NICs, examine Cisco’s new partnership with Hugging Face to scan every open‑source AI model for malware, and break down Broadcom’s Jericho4 fabric router—bringing 3.2 Tb/s “hyper‑ports” to distributed AI clusters. The hosts also discuss the real‑world state of SD‑WAN adoption, Palo Alto Networks’ $25 B CyberArk acquisition, Cisco’s quantum‑networking research, and upcoming industry events. Plus: a personal tale of basement‑automation triumph to kick things off.

Phil Gervasi sits down with Kentik Product Marketing Manager Eric Hian-Cheong to discuss why data enrichment is the "secret sauce" that turns raw flow logs, metrics, and cloud telemetry into true network intelligence. They explore how tagging telemetry with human-readable context—such as customer names, app IDs, Kubernetes labels, and more—shrinks mean-time-to-insight, empowers cross-team troubleshooting, and lays the groundwork for AI-driven operations.

In this Telemetry News Now episode, Phil and Justin cover the global Cloudflare DNS outage, a rumored $10B SentinelOne acquisition by Palo Alto Networks, submarine cable security concerns from U.S. lawmakers, a major Alaska Airlines data center failure, why some say data centers are obsolete before they open, and Arista’s latest strategic hire. Plus, upcoming events and industry insights.

Ryan Booth, network engineer and AI developer, joins Philip Gervasi to explore the practical realities of building AI applications specifically for network and IT operations. They talk about the importance of starting with clear business objectives, understanding data engineering essentials, managing model evaluation, and bridging knowledge gaps between infrastructure and data teams. Ryan shares his insights about the need for iterative learning, using simple projects to gain practical skills, and recognizing how AI can effectively solve real ITOps and NetOps challenges.

In this Telemetry News Now episode, Phil and Justin cover Cisco’s big legal win, HPE’s finalized Juniper acquisition, Arista’s strategic move to buy VeloCloud, CoreWeave’s $9B play for AI-ready data center infrastructure, Google’s new transatlantic subsea cable, Rackspace’s AI-focused private cloud, and yes—TSA may finally let you keep your shoes on.

In this Telemetry News Now episode, Phil and Justin discuss the future energy demands of AI infrastructure, including eye-opening predictions about GPU power consumption. They discuss Gartner's skepticism regarding agentic AI projects, cautioning against inflated expectations. The duo also covers Cisco's latest quantum networking moves, legal battles over AI data rights, innovative private 5G networks at UK ports, and new high-capacity networking investments in Scandinavia. Plus, updates from Panama's internet shutdown and the latest industry events.
