In this episode of Ship Happens, host Per Krogslund sits down with Sergey Katsev, VP of Engineering at Catchpoint, for a deep dive into internet performance, distributed systems, and the realities of modern engineering management.

Sergey explains why today’s websites rely on a sprawling network of dependencies — DNS providers, CDNs, cloud infrastructure, APIs, analytics, and third‑party scripts — and why traditional monitoring fails to capture real user experience. At Catchpoint, thousands of global “vantage points” act like automated secret shoppers, mapping outages, latency, and hidden bottlenecks before customers feel them.

Per and Sergey explore why DNS remains one of the most fragile, overlooked layers on the internet, with recent large‑scale disruptions proving how easily the web breaks. From dependency chaos to observability as a shared language, Sergey reveals why systems thinking is the most important skill for today’s engineers and managers.

They also unpack engineering leadership essentials:

This episode blends internet architecture, leadership philosophy, and the future of engineering work — offering a grounded look at how modern teams can navigate complexity and build more resilient systems.
