When Cloudflare Sneezes, the Internet Catches a Cold

-

November, 2025 was one of those times that reminded me just how fragile the internet really is. Cloudflare, one of the biggest internet infrastructure companies had a major outage, and for a moment, it felt like half the web just… stood still.

Websites wouldn’t load. Apps were timing out. And I just sat there thinking: “Wow. So one company’s hiccup can freeze thousands of websites at once.”

But let me break it down properly.

What happened with Cloudflare?

Cloudflare, for anyone new to the name, basically acts as a protective middle layer between websites and the internet. They handle security, speed, and protection from attacks.

So when Cloudflare went down, websites that rely on it didn’t just slow down, many became completely unreachable.

The internet looked fine… until you tried visiting any site using Cloudflare. Then suddenly, everything broke.

For example:

  • Websites wouldn’t load.

  • Some apps wouldn’t connect to their backend servers.

  • API-heavy services stopped responding.

In simple terms: Cloudflare had a bad day, and the internet had a worse one.

What this outage really means

Seeing so many platforms go down at once taught me something important:
the internet is way more interconnected than we think.

I also discovered something new during the chaos - DownDetector.

DownDetector is a site that lets you see when popular platforms are suddenly having issues. The moment Cloudflare had problems, DownDetector lit up like a Christmas tree. Almost every major service had a spike in outage reports.

And that’s when it clicked for me:
If one key infrastructure provider goes down, the ripple effect can hit the whole world.

It’s like taking out a major power station. Even if your house is fine, your lights still go off.

This is especially worrying for websites that depend heavily on Cloudflare. If Cloudflare is down, they go down with it. That dependency can quickly become a weakness.

What I learned from the incident

This outage wasn’t just a “tech issue.” It was a lesson, at least for me.

1. Redundancy is everything

If your entire system rests on one CDN, one DNS provider, one security layer…
you're one outage away from trouble.

Having a backup or secondary CDN isn’t optional anymore, it’s survival.

2. Monitor the monitors

Thanks to DownDetector, I now understand how outages ripple across the internet. I didn’t even know it provided real-time insights like that. Now I’m adding it to my personal monitoring toolkit.

3. One provider shouldn’t hold this much power

The Cloudflare outage showed me how centralised the internet has become. A single infrastructure failure shouldn’t be able to affect so many services at once — but here we are.

Final thoughts

The internet may feel huge, but incidents like this remind me how tightly connected everything is. As someone getting deeper into cybersecurity, moments like these make me appreciate resilience, redundancy, and proactive planning even more.

Because when Cloudflare sneezes?
The internet really does catch a cold.

How I Passed the Cisco Introduction to Cybersecurity Course: My Experience & Tips

-
Cybersecurity is an ever-growing field, and as someone transitioning into it, I knew I had to start with the basics. That’s why I took the Cisco Introduction to Cybersecurity course. In this post, I’ll share my experience, key takeaways, and tips for anyone considering this course. As a beginner in cybersecurity, I wanted a structured way to understand the fundamentals. Cisco Networking Academy offers well-recognized courses, and this one seemed like the perfect starting point. What I Learned The importance of cybersecurity in today’s digital world. Different types of cyber threats and how they impact businesses and individuals. Basic security principles like the CIA Triad (Confidentiality, Integrity, Availability). Career paths in cybersecurity and the required skills. My Learning Process Consistency: I dedicated a specific time each day to study. Taking Notes: Writing down key points helped me retain information. Practice Questions: I reviewed quizzes and assessments multiple times. ...

Packets, Clues, and Coffee: A Wireshark Investigation Story

-

Sometimes the best way to learn is to get your hands dirty. That’s exactly what I did when I tackled a Malware Traffic Analysis exercise. It wasn’t just another packet capture, it was a crime scene, and my job was to figure out who did what, when, and how. Setting the Scene The packet capture (PCAP) was buzzing with background noise from routers, smart devices, and other chatter. My mission? Find the infected Windows machine, figure out who used it, identify any fake websites it reached out to, and uncover the command-and-control (C2) servers that kept the infection alive. Step 1: Finding the Infected IP My first move was to clean up the view in Wireshark. I didn’t want to see every little broadcast or IoT heartbeat. I only cared about web traffic, both HTTP and HTTPS. So I used this filter: (http.request or tls.handshake.type eq 1) and !(ssdp) This simple line told Wireshark, “Show me only the good stuff.” And just like that, the infected client revealed itself:...

Cyberwarfare in the Russia-Ukraine Conflict

When we think of war, most of us picture soldiers, bombs, and tanks. But in today’s world, there’s another battlefield that we often forget. The cyberspace. And the Russia-Ukraine conflict has shown us just how real and powerful cyberwarfare can be. Even before the physical war escalated, Ukraine was already being hit by cyberattacks. These weren’t random hacks. They were deliberate, organized, and meant to weaken the country. One example that still stands out is the NotPetya malware attack in 2017. It started in Ukraine but quickly spread around the world, crippling companies and governments, and causing damages of over 10 billion dollars. That was a clear sign that a cyberattack in one country could shake the entire globe. Fast forward to 2022, when the conflict reached new heights. Ukraine faced DDoS attacks on government websites, data-wiping malware targeting critical systems, and even attempts to shut down its energy grid and financial institutions. The goal was clear: disru...
