LibreQoS greatly improves the quality of experience of internet connections. It was born out of necessity during the COVID pandemic when massively increased internet usage resulted in intermittent package loss. Robert Chacón, CEO of LibreQoS and operator of a small ISP that provides internet to under-served communities, noticed how it affected his customers’ ability to work from home and do online learning. In response, LibreQoS was created to fight bufferbloat and latency issues by prioritizing interactive sessions like video calls over, say, downloading large files.

In this episode we speak to Robert, Herbert Wolverson (Chief Product Officer), and Frantisek Borsik (Chief Operating Officer). They talk about how they open sourced LibreQoS in the hopes of helping other small ISPs who bring internet to the under-served, and their surprise at the rapid rise in popularity with deployments in 58 countries. They provide insight in the world of ISPs, and how stable internet connections aren’t just about good gaming experiences but can actually save lives.

In loving memory of Dave Täht
Sadly, Dave Täht passed away days after the recording of this episode. Dave was Chief Science Officer at LibreQoS and made fundamental contributions to FQ-CoDel, CAKE, and LibreQoS to improve the internet for everyone. He worked to make real-time communication available everywhere and insisted his code be free and open source so it would truly benefit everyone. He is remembered by many for who he was and the lives he touched with his work on his memorial page.
