What to check
Backup design by failure scenario
Name the outage first; then select the second path and recovery method.
| Failure to protect | Design response | Test |
|---|---|---|
| Building fibre cut | Different physical access technology or route | Disconnect primary at the edge |
| Provider or upstream failure | Independent provider and path where possible | Health-check and application recovery |
| Local power failure | UPS for both access and network equipment | Timed power-loss test |
Map the failure domains
- Provider network
- Building fibre entry and riser
- Site power and UPS runtime
- Router or firewall
- DNS and identity services
- Wi-Fi and switching
- Cloud application dependencies
Ask for a witnessed failover test
Disconnect the primary path during an agreed window. Record detection time, switch time, application recovery, session loss and return-to-primary behaviour. A dashboard saying “backup online” is not proof that the payment terminal or VPN works.

Document one planned fibre interruption and the measured effect of a satellite or 5G backup on WMS, scanners, CCTV and voice.
Questions people ask
How fast should business internet failover happen?
Set the target from the application and downtime risk. Some sessions can recover automatically; others require reconnection or user action. Test the actual firewall, DNS, VPN, voice and cloud workflows.
Should the backup use the same building entry as fibre?
That can preserve a shared physical failure. If route diversity matters, document the cable entry, local power and upstream dependencies instead of relying only on different provider names.
Can a UAE business use a residential Starlink plan?
Starlink’s published plan descriptions should be checked for the intended use. Do not select a household plan for business or enterprise work unless the current official terms explicitly permit it.
