Datadog Went Dark for 24 Hours and Came Back With a Different Philosophy

On March 8, 2023, Datadog — the platform engineers use to know when their own infrastructure is broken — broke.

The people whose job was to fix it couldn't see what was happening. It cost $5 million. It changed how Datadog thinks about building software.
