Building a Redundant Network That Actually
Stays Up
Redundancy sounds expensive. It can be. But
it doesn't have to bankrupt your IT budget to
achieve meaningful uptime improvements.
We've put together this guide based on real
implementations across retail shops, medical
clinics, and small manufacturing facilities
in Northern Thailand. Each faced different
constraints but needed the same outcome —
less downtime without doubling their network
budget.
The approach involves three layers of
thinking: what fails most often (spoiler:
it's usually power or the ISP), what you can
reasonably duplicate within budget, and what
monitoring you need to know when the backup
isn't actually backing anything up.
You'll also find our calculator for
estimating downtime costs, which helps
justify the investment to management. Because
"we should have redundancy" doesn't work as
well as "30 minutes of downtime costs us X
baht in lost transactions."
