Building a resilient home connection
Failover, battery backup and sensible redundancy for people who work from home — without building a data centre in a cupboard.

Resilience is mostly about removing cheap single points of failure and accepting the ones that are not.
A small UPS keeps a router and ONT running for several hours and covers the majority of short power cuts.
A router with automatic failover to a mobile SIM can take over within seconds, which is usually enough to keep a call alive.
Keep a second DNS resolver configured. Many home networks break quietly during an incident at this layer.
You do not need enterprise hardware. A mid-range router with failover, a modest UPS and a cheap standby SIM is a reasonable starting point for most households.
Editorial note
This article is editorial guidance. Where a result depends heavily on location we say so rather than reporting a single number as universal.
