Definitions

  1. A casual phrase for the lowest layers of a technical stack, such as infrastructure, operating systems, runtimes, or foundational libraries. In engineering slang, problems at the bottom of the stack usually imply something harder to isolate and easier to blame broadly.

    Example: "The symptoms looked like an app bug at first, but the root cause was at the bottom of the stack in the storage layer's timeout handling."
