Honeycomb Observability Day

6-7 October, 2026

London

Real talk from real practitioners

The rules of production are changing. AI is introducing complexity that traditional approaches to observability were never designed for and the teams leading this shift have the deepest understanding of their systems.

O11yDay London is where developers and engineering leaders come together to share what’s actually working in the agent era: Real challenges, real learnings, real outcomes. Two days of honest sessions, hands-on workshops, and a community of practitioners who get it.

Sam Newman
Dark Software Factories

Keynote
Author of Building Microservices and Monolith to Microservices, Sam has spent years helping organisations understand how their systems actually behave in production.

His keynote explores the hidden complexity accumulating inside AI-augmented systems and what we need to do about it.

Corey Quinn
Tokenomics

Corey is Chief Cloud Economist at The Duckbill Group and one of the most sharp-tongued voices in cloud infrastructure.

He’ll be unpacking the real cost structures emerging as AI workloads hit production, because tokens aren’t free, and pretending otherwise is expensive.

Yana Chen — Inference Reliability at Cloud Scale

Yana leads infrastructure at Baseten, where inference reliability isn't a nice-to-have, it's the product.

She'll be sharing hard-won lessons from running ML inference at scale: what breaks, what doesn't, and how you actually debug it.

Brian Scanlan
AI Developer Productivity

Brian is an engineering leader at fin.ai, where the team is navigating what AI-assisted development actually looks like day to day.

He’ll share what’s changed, what hasn’t, and how observability fits into a workflow where more of the code is generated than written.
