When it comes to running a reliable IT infrastructure, network devices are at the center stage.

When a website goes down, the failure often feels like a black box. Visitors see a spinning wheel, a cryptic error code, or a blank page. For the people responsible for keeping that site online, the first question is always the same: what broke?

Each step depends on the ones before it.
