System Error black outline icon

About the System Error black outline icon

A triangular caution sign holding a bold exclamation mark sits behind a toothed cogwheel that overlaps its lower right corner, so a mechanical fault and an alert appear as one mark. It reads as system error, application crash, engine failure, hazard warning or service downtime, and fits 404 and 500 pages, maintenance screens, DevOps dashboards, machine control panels and IT support documentation.

The triangle uses softly rounded corners and a centered exclamation with a separate dot, while the gear shows eight square teeth and an open hub. Set it next to settings, bug and server icons; a clear cutout keeps the two shapes separate below 32px.

This is the black outline version of the system error icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
