System Error black filled icon

About the System Error black filled 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 solid black filled version of the system error icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
