What happens when your internet drops — and how to keep trading
Why a single outage can stop a modern business, and the simple backup that prevents it.
Think about everything that runs over your internet connection: card payments, phones, bookings, email, cloud files, even the security cameras. When the line goes down, most of your business goes with it — and the cost adds up fast in lost sales and idle staff.
What actually stops
You can’t take payments, customers can’t call, staff can’t reach the systems they need, and online orders stall. For a retailer at lunchtime or a clinic mid-appointment, even 30 minutes offline is a real hit.
The fix: automatic failover
Failover means a second connection takes over the instant your main one fails — automatically, without anyone flicking a switch. Done well, most people never even notice the drop.
4G/5G internet failover
A mobile data connection stands by; if your NBN fails, traffic reroutes to it in seconds, keeping EFTPOS, email and cloud apps alive.
Cloud phones that reroute
With a cloud phone system, calls automatically jump to the mobile app on your team’s phones — so customers still get through even if the office is dark.
A backup data SIM
A data-only SIM on the Telstra Mobile Network (from $27.50/mo) is a low-cost insurance policy that’s ready the day you need it.
Build your continuity plan with Comstel
We’ll map what your business depends on, then set up the right backup — business NBN with 4G/5G failover, cloud phones that reroute, and a standby data connection — so an outage becomes a non-event.
Quick continuity checklist
- Do you have a second, independent connection (not just one NBN line)?
- Does failover happen automatically, or does someone have to notice first?
- Will your phones keep working if the office internet is down?
- Can you still take payments during an outage?
- Have you actually tested it — not just assumed it works?
