The Day I Could Not Buy Lunch
April 28, 2025 began like any other Monday.
I was at home in Spain, midway through a Google Meet. Two laptops open. Calendar full. The kind of morning you never expect to remember.
One of the laptops, usually left unplugged because there is always power, suddenly went dark.
Battery drained, I assumed.
I plugged it in.
Nothing.
A moment later, the laptop I was actively using froze. My face locked mid expression. In the corner of the screen, a small notification appeared: ‘No internet connection.’
I reached for the light switch.
Nothing.
The power was gone.
I picked up my phone to text my colleagues on WhatsApp, so that i could let them know what was going on.
No data signal.
I tried calling.
Nothing.
I toggled airplane mode. Restarted. Waited.
Still nothing.
I stepped outside and walked around, looking for a signal.
Traffic lights were dark. Cars edged cautiously into intersections while police officers directed traffic by hand. People were outside their buildings.
Nothing.
Back inside my apartment, the implications began stacking up.
My stove is electric. I couldn’t cook. The microwave wouldn’t turn on.
What started as a dropped meeting was becoming something larger.
By midday, I walked to a nearby cafe to get lunch with a friend whose travel plans for the day had been cut short.
The doors were open. The staff were there.
But the POS and contactless systems were down. No network. No transactions.
I rarely carry cash, I misplace it more often than I’d like to admit. Most of us don’t anymore.
We had money in our bank accounts. But without cash, and without network connectivity, that money was inaccessible.
I wasn’t the only one standing there unable to pay. Our ability to obtain something as simple as lunch depended entirely on systems we do not control.
At that point, it was still unclear how widespread the outage was. As updates began to circulate, the scale came into focus.
From Personal Disruption to National Impact
With power and connectivity down at the same time, my mind went to the same place many people in my field would go. Was this a cyberattack?
Authorities later ruled out malicious cyber activity. But in the first hours, the question didn’t feel dramatic. It felt rational. In a system where software coordinates critical infrastructure, simultaneous failure is no longer assumed to be accidental.
Within hours, the scale became clear.
Nearly the entire Iberian Peninsula went dark.
Madrid. Barcelona. Valencia. Sevilla. Zaragoza. Lisbon. Porto. Entire urban centers lost power.
116 trains were halted mid-journey in Spain alone. 35,000 rail passengers were stranded. Airports operated at severely reduced capacity. Telecommunications traffic dropped to 17% of normal levels. Hospitals switched to generators. Banking systems were disrupted. Businesses and schools closed.
Public life effectively paused.
Economic losses were estimated at €1.6 billion.
At least 7 people died, including 3 from carbon monoxide poisoning related to generator misuse and 1 in a house fire.
This was not a local outage.
It was a cascading infrastructure event.
Technology is no longer a convenience layer on top of society.
It is now foundational infrastructure.
The Interdependence We Engineered
Digital systems once supported operations quietly in the background. Today, they are the operations.
Infrastructure that used to be mechanical is now software driven. Systems that were once isolated are now networked.
Modern systems are tightly couple.
Power enables telecommunications.
Together, they coordinate transport.
Transport supports commerce.
Commerce underpins finance.
Finance sustains healthcare.
Healthcare depends again on power and networks.
When power failed, telecommunications degraded almost immediately.
Cell towers have battery backups, but they are designed for limited continuity. Core routing infrastructure depends on stable grid power and fiber networks. As grid stability faltered, telecom traffic dropped to 17% of normal levels.
Transport stalled.
Commerce froze.
Payments failed.
Participation stopped.
These systems are layered and interdependent. They do not operate in isolation.
When one dependency weakens, others compensate. When several weaken at once, it compounds.
That compounding effect is what turned a technical disruption into a societal pause.
When Technology Becomes a Basic Need
For most of human history, basic needs were tangible. Food. Water. Shelter. Healthcare.
Today, reliable power and digital connectivity belong on that list.
When power disappeared, connectivity followed. And with them, so did:
- Communication
- Payment systems
- Transportation mobility
- Remote work capability
- Access to information
- Coordinated emergency response
Technology is no longer something we merely use.
It is something we depend on to function.
Security Is Not an IT Process Anymore
When digital systems were confined to corporate networks, cybersecurity could remain an IT responsibility.
That boundary no longer exists.
Digital systems now operate: Power grids, Rail networks, Aviation systems, Financial clearing platforms, Healthcare infrastructure.
Software decisions influence physical outcomes.
When a payment terminal fails, that is not only an IT issue. It prevents a transaction in the physical world.
Security is no longer just about protecting data.
It is about safeguarding continuity.
As dependency increases, risk aggregation increases.
Technology has extended life expectancy, expanded knowledge, connected markets, and accelerated growth at unprecedented scale.
But essential systems require foundational protection.
When It All Came Back
The restoration was quiet.
Router lights blinked on. Signal bars reappeared. My phone vibrated as queued emails, messages, and missed call notifications flooded back in. Traffic lights resumed control. Card terminals beeped. WiFi stabilized.
Within minutes, the city returned to normal operation.
Everything resumed where it had paused.
The outage did not just feel dramatic.
It also felt instructive.
For 10 hours, I was not missing luxuries.
I was missing function.
Modern life now relies on systems that must remain continuously available.
And when technology becomes a basic need, securing it is not optional. It is our responsibility.
