Observability isn't a tool you buy anymore, rather it's a property of the platform you build.

If I had to summarize 2025 in a sentence, it would be that observability finally matured from a data business into a systems problem again.

Every server at Meta runs eBPF, 50% over 180 programs and they run on average across 20 different kernel versions

I think we will see more and more companies heading this way so check out this talk to see how they needed to re engineer their CI/CD pipeline

My alma mater uses Cilium 🐄 I wonder if these clusters help with ice cream production 🍦

"Cilium has been phenomenal. We started with core networking, added Hubble for observability, Cluster Mesh for cross-cluster communication, and are exploring Tetragon"

eBPF dev room schedule for FOSDEM 2026 is out 🐝

eBPF has become a normalized building block for infrastructure so if you want a single room that spans kernel internals, language tooling, observability, and networking, I'll see you in Brussels over a beer 🍻

Happy 10th Birthday, Cilium! 🎂

One decade ago, Thomas Graf pushed an initial commit with just a LICENSE, a .gitignore, and 226 lines of code. There was no Hubble, no Cluster Mesh, no network policy, no Tetragon, and eBPF still had a logo with a pea pod in it.

I'm at Linux Plumbers Conference in Tokyo this week to talk about what the eBPF Foundation accomplished this year and get feedback from the community on what we should focus on next

If you can't make, let me know what you think is currently holding eBPF back so the foundation can work to fix it 🐝
