The card machine hangs at the till. The video call freezes mid-pitch. The booking system refuses to load, and someone in the office says what everyone says: “It must be the Wi-Fi.”
Sometimes it is. But often, the problem sits much further back, in places most business owners never see.
The services businesses use every day rely on more than a fast connection. They also depend on servers, data storage and a steady supply of electricity.
Internet Access Is Only the Front Door
Broadband and mobile data are the parts of digital infrastructure people notice. They are the front door.
Behind that door sits a lot of physical equipment. Emails, payment platforms and customer databases all run on servers in buildings that need power and cooling around the clock.
“The cloud” can make this feel abstract. In reality, it simply means your data and software live in someone else’s building.
As more Manchester businesses move towards cloud-first operations, the condition of those buildings matters more, not less.
When the Power Behind Digital Services Falters
Think about what a typical business relies on in a single day. Staff message customers, card payments go through, orders are tracked and stock is updated.
When power to the infrastructure behind these tasks is interrupted, the effects go beyond losing the internet. Transactions can fail, records can become unavailable and customers may be unable to reach the business at all.
The North Hyde substation fire in west London in March 2025 showed how far one failure can travel. The National Energy System Operator’s final report found it cut supply to 66,919 directly connected customers and led to the closure of Heathrow Airport.
Data centres face similar pressures. The Uptime Institute’s 2026 Annual Outage Analysis found that power remains the leading cause of impactful outages. In its 2025 survey, 57% of respondents said their most recent major outage cost more than $100,000.
The same report notes that outage frequency per site has fallen for five years running. Failures are becoming less common, but they tend to be costly when they happen.
Why Data Centres Are Treated as Critical Infrastructure
The government has recognised how much the economy now leans on this hidden layer. In September 2024, UK data centres were designated as Critical National Infrastructure, placing them alongside energy and water systems.
The status brings closer coordination with the government during incidents such as cyber attacks, IT blackouts and severe weather. The buildings storing the nation’s data are now seen as essential, not just useful.
How Data Centres Prepare for Power Interruptions
Most data centres plan on the basis that mains power will, at some point, fail. Their response usually relies on two systems working together.
The first is the uninterruptible power supply, or UPS. It uses batteries to keep equipment running the instant mains power drops, covering the first seconds or minutes of an outage.
The second is the standby generator. Once running, it takes over the load through automatic changeover switching and can keep the site going for as long as fuel allows.
Neither system works well in isolation. A UPS buys time but cannot run a site for hours. A generator can, but needs a short window to start. Together, they close the gap.
The equipment is only part of the picture. Testing, maintenance and fuel management matter just as much. That is why planning for data centre standby power tends to focus on how systems perform under real conditions, not just on paper.
What This Means for Manchester Businesses
Most firms will never run a data centre, but almost all of them depend on one. A few practical steps can help:
- Ask your hosting and software providers where your data is held and how those sites are protected against power loss.
- Check what your own premises can keep running during a power cut, from comms cabinets to card terminals with offline modes.
- Include power disruption in your continuity plan, not only cyber threats.
These questions are not about expecting the worst. They are about knowing where the weak points are.
The Connection Is Only Half the Story
The next time the card machine stalls, the broadband may well be to blame. But Manchester’s digital economy runs on far more than the speed of its connections.
Electricity, data centres and backup systems all play a quiet role in keeping businesses trading. As firms across the city region become more digitally dependent, that less visible infrastructure deserves a place in the conversation.
