Learn from Various (Linux OS)

Remember when a single second
brought down Reddit and LinkedIn?

On June 30, 2012, the introduction of a leap second triggered a kernel timing bug in Linux, leading to widespread server lockups. Incident Drill lets your team practice responding to similar OS-level incidents in a safe, controlled environment.
