Continuity of access.
WHY CONSIDER ONE
An outage stops everything: cards, calls, systems, orders.
WHAT THE OPTIONS ARE
A second fixed connection, preferably on different infrastructure A mobile connection as a fallback Manual failover using a phone's connection
WHAT MATTERS MOST
That the fallback does not share the same failure.
Two services over the same physical route fail together.
HOW FAILOVER WORKS
Some routers switch automatically when the primary fails.
Otherwise it is manual.
WHAT TO TEST
That failover actually works, before you need it.
Disconnect the primary and see.
WHAT TO EXPECT FROM A MOBILE FALLBACK
Lower capacity and possibly metered.
Sufficient for essential work, not for everything.
WHAT TO PRIORITISE DURING AN OUTAGE
Payments, communication, and anything customer-facing.
WHAT TO PREPARE
Who switches it, and how.
WHAT TO DOCUMENT
The procedure, somewhere reachable without the network.
