Where outages happen
Connectivity depends on several layers: your device, router, local access network, ISP routing, DNS, cloud platforms, and power. A failure at one layer can look like the whole internet is down.
Compare symptoms across devices, networks, and services. If cellular works but home broadband fails, the likely layer differs from a widespread cloud or DNS incident.
