What happens when your platform faces 30 times more traffic than usual — and the regular dashboards aren’t enough? Twice a year, our e-commerce platform enters a high-stakes period we call “the Archives” — an intense sales event that pushes our systems to their limits. During our most recent edition, we broke all previous records… and hit performance ceilings we had never encountered before. In this talk, I’ll share how our team prepared for the unexpected, how Datadog helped us cut through the noise in real time, and how we detected a subtle yet critical issue that could have gone unnoticed — hidden in a storm of data. You’ll walk away with concrete ideas on how to monitor for edge cases, design alerts that matter during chaotic traffic spikes, and build resilience for days when “normal” doesn’t apply.
