Keeping Systems Running Through Power and Internet Cuts

How to Build Systems That Keep Working Through Power and Internet Cuts

Power cuts and weak internet are part of the working day in many parts of Syria. This article explains how to set up your devices, software and procedures so that sales do not stop and data is not lost with every outage.

How do I keep my company’s systems running through power and internet cuts?

Combine three layers: power protection for key devices such as the server, router and point of sale; a backup internet connection; and software that can work offline and sync the data when the connection returns. Add a written procedure every employee knows for what to do during an outage.

The power layer

Identify critical devices: Not every device needs protection. Start with the server, the router, the points of sale and the accounting computer.
Uninterruptible power supply (UPS): Gives a short window, enough to save work and shut devices down properly, and protects against power surges when the supply returns.
Batteries and solar power: To keep working for hours during an outage, the office needs a battery or solar system sized for the critical devices only.
Automatic safe shutdown: Set the server to shut itself down properly before the battery runs out. A sudden shutdown can damage data and drives.

The internet layer

A backup line: A second line from a different provider, or a mobile data package, can save the working day when the main line fails.
A router that switches automatically: Some routers move to the backup line without anyone touching them, which saves staff time and confusion.
Use bandwidth wisely: Schedule large updates and big uploads for quieter hours, and block unnecessary use on the work network.
Keep an outage log: Record when the connection drops for a few weeks. This log helps you choose a better provider or a more suitable package.

The software and procedures layer

Software that works offline: Good point-of-sale and field apps save transactions locally and send them when the internet comes back.
Do not rely on the browser alone: If your system only works online, ask the provider about an offline mode or a local version.
A numbered backup book: For recording sales during long outages, with one employee responsible for entering them into the system later.
A one-page plan: A sheet on the office wall showing who shuts down what, who informs customers, and how transactions are recorded until service returns.

An outage plan in five steps

01
List devices and systems
Write down what must always run and what can wait until the power comes back.
02
Estimate the power load
Ask a qualified technician to calculate what the critical devices draw, so you choose a UPS and batteries of the right size.
03
Secure a backup line
Choose a provider or technology different from the main line, so both do not fail at once for the same reason.
04
Test the software offline
Disconnect the internet on purpose and try selling and recording, then reconnect and confirm all data arrives with no duplicates.
05
Train the team
Run a short drill of the outage plan so every employee knows exactly what to do.

What each device needs

Device	Suggested protection	Note
Server	UPS with automatic safe shutdown, plus backups	A sudden shutdown is more dangerous for it than the outage itself
Router and modem	A small UPS or a dedicated battery	Low power draw, and keeping it on keeps you connected
Point of sale	UPS and software that works offline	Make sure invoices sync after the internet returns
Desktop computers	Surge protection and automatic file saving	A laptop is a practical alternative for some roles because it has its own battery

Frequently asked questions

Is a UPS enough to run the office during an outage?

Usually not. A UPS is designed to give you time to save work and shut down safely. To work for hours you need larger batteries or a solar system.

With frequent outages, is a cloud or a local system better?

It depends on the type of outage. If power at the office is the problem, the cloud protects the data. If the internet is the problem, a local or hybrid system keeps work going.

How do I know the software really works offline?

Ask for a live demo where the network is disconnected in front of you, then reconnected, and check that every transaction arrives with no duplicates or losses.

What do I do with transactions recorded on paper during an outage?

Assign one employee to enter them as soon as service returns, and number the pages so no transaction is missed.

Can you help us design systems that cope with outages?

Yes. ONE DIGITAL’s branch in Hama can review your systems and suggest a setup that suits your power and internet conditions.
