Dubbed “The man who can see the internet” by the Washington Post, Doug Madory has made significant contributions to the field of internet measurement. In this post, we explore how internet measurement works and what secrets it can uncover.

Testing NetFlow used to require time, expertise, and lab equipment. Using Kentik and the new Kappa agent, it can be done in minutes with nothing more than a spare Linux machine.

The network is the metaphorical plumbing through which all your precious non-metaphorical observability and monitoring data flows. It holds secrets you’ll never find anywhere else. And it’s more important today than ever before.

NANOG 91 gathered network professionals to discuss emerging trends and challenges in networking. The event featured keynotes and technical sessions focused on critical areas such as cloud-induced network complexities, the advent of network digital twins, IPv6 deployment, network automation, and BGP routing security. In this post, Justin Ryburn, Field CTO, summarizes his takeaways from the event.

Multi-cloud visibility is a challenge for most IT teams. It requires diverse telemetry and robust network observability to see your application traffic over networks you own, and networks you don’t. Kentik unifies telemetry from multiple cloud providers and the public internet into one place to give IT teams the ability to monitor and troubleshoot application performance across AWS, Azure, Google, and Oracle clouds, along with the public internet, for real-time and historical data analysis.

The 2024 EMA Network Megatrends surveyed hundreds of IT professionals about their approach to managing, monitoring, and troubleshooting their networks. In this post, we examine the report’s findings to learn the business and technology trends shaping network operations strategy.

Cloud costs are spiraling out of control at companies of all sizes. Here’s how to not let your cloud infrastructure costs handcuff your business.

In RPKI, determining when exactly a ROA expires is not a simple question. In this post, BGP experts Doug Madory and Fastly’s Job Snijders discuss the difference between the expiration dates embedded inside ROAs and the much shorter effective expiration dates used by validators. Furthermore, we analyze how the behavior effective expiration dates change over time due to implementation differences in the chain of certificate authorities.

Hybrid cloud environments, combining on-premises resources and public cloud, are essential for competitive, agile, and scalable modern networks. However, they bring the challenge of observability, requiring a comprehensive monitoring solution to understand network traffic across different platforms. Kentik provides a unified platform that offers end-to-end visibility, crucial for maintaining high-performing and reliable hybrid cloud infrastructures.

We’re excited to announce a new collaboration between Kentik and Red Hat. This partnership will enable organizations to enhance network monitoring and management by integrating network observability with open-source automation tools.
