Distributed Denial of Service (DDoS) attacks used to be the kind of thing that made headlines once in a while – large banks, governments, or global tech giants brought to a halt by sheer force of traffic.
That’s no longer the world we’re operating in.
Today, DDoS attacks are constant, industrialised, and increasingly accessible. In 2025 alone, more than 47 million attacks were recorded globally, with an average of over 5,000 attacks every hour, according to Cloudflare’s latest DDoS threat reporting.
What was once exceptional has become routine.
And this week’s disruption to Ubuntu services, widely reported by outlets including TechRadar and TechCrunch, is a clear reminder of just how widespread and indiscriminate these attacks have become.
A Real-World Wake-Up Call
Ubuntu, one of the world’s most widely used Linux distributions, alongside its parent company Canonical, experienced a sustained DDoS attack that disrupted core services.
For nearly a full day, users reported being unable to:
- Install or update systems
- Access security APIs
- Reach key web infrastructure
The attack was claimed by an Iraqi hacktivist group – The Islamic Cyber Resistance in Iraq 313 Team – reportedly using a DDoS-for-hire platform, highlighting a growing trend: you no longer need deep technical expertise to launch a high-impact attack.
If a globally trusted, widely distributed platform like Ubuntu can be affected, it raises an uncomfortable question: How prepared is the average organisation?
What a DDoS Attack Really Looks Like
At its simplest, a DDoS attack is about overwhelming a system with traffic. But the scale and sophistication have evolved dramatically.
A useful way to think about it:
Imagine a stadium-sized crowd of automated devices, all trying to access your service at the exact same moment. Legitimate users don’t get blocked by a firewall, they get drowned out.
These attacks are powered by botnets – networks of compromised devices that can include:
- Servers and cloud instances
- IoT devices
- Even everyday consumer tech like smart TVs
In recent campaigns, botnets comprising millions of infected devices have generated traffic at levels previously thought impossible.
Why DDoS Attacks Are Surging
Several forces are driving this rapid escalation:
1. The Rise of “DDoS-as-a-Service”
Attack tools are now commercially available, often marketed as “stress testing” services. For as little as £10 (approx. $13/€11) per month, attackers can launch coordinated attacks at scale, something highlighted in recent reporting on the Ubuntu incident.
2. Hacktivism and Geopolitics
DDoS is increasingly used as a tool for signalling, disruption, or retaliation, making organisations potential targets regardless of size or sector.
3. The Explosion of Connected Devices
Every unsecured device is a potential botnet node. From home routers to Android-based systems, the attack surface is vast and growing.
4. Cloud Infrastructure Abuse
Ironically, the same scalable infrastructure that powers modern digital services is also being leveraged to launch attacks, adding both scale and legitimacy to malicious traffic.
Bigger, Faster, Harder to Stop
It’s not just the number of attacks increasing, their intensity is also reaching new extremes.
- Hyper-volumetric attacks have grown by over 700%, according to Cloudflare data
- Peak attack sizes have exceeded 30 Tbps, with record-breaking events disclosed in late 2025 by Cloudflare
- Some attacks now generate hundreds of millions of requests per second
To put that into perspective: a single attack can simulate the combined activity of entire countries hitting a service simultaneously.
The United Kingdom itself has rapidly climbed the rankings of most-targeted regions, underlining that this is not a distant problem, but a local and growing one.
Mitigating the Threat: What Actually Works
Defending against DDoS attacks isn’t about a single tool or tactic – it requires a layered, always-on approach.
Real-Time Detection and Automation
Modern attacks move too fast for manual response. Effective mitigation depends on systems that can detect and respond in real time.
Traffic Filtering and Rate Limiting
Separating legitimate users from malicious traffic is critical, without degrading performance.
Scrubbing and Rerouting
Malicious traffic needs to be diverted and cleaned before it reaches core infrastructure.
Global Scale
DDoS protection is ultimately a scale problem. The ability to absorb and distribute traffic across a global network is essential.
Always-On vs On-Demand Protection
On-demand mitigation can help in specific scenarios, but increasingly, organisations are moving towards always-on protection to ensure continuous resilience.
Designing for Resilience
The key takeaway isn’t that DDoS attacks are getting bigger, it’s that they’ve become part of the normal operating environment.
They are:
- Frequent
- Accessible
- Increasingly automated
- And often indiscriminate
Which means resilience can’t be reactive – it has to be designed in.
How vXtream Helps
At vXtream, DDoS mitigation is built into the foundation of the network, not bolted on as an afterthought.
All Elastic Compute customers benefit from baseline DDoS protection, while organisations with higher risk profiles can leverage:
- On-demand enterprise mitigation with intelligent traffic rerouting and scrubbing
- Always-on protection with continuous monitoring and automated response
- Support from global Security Operations Centres (SOCs) operating 24/7
The goal is simple: ensure that malicious traffic is removed before it impacts performance, availability, or user experience.
The question is no longer if your organisation will experience a DDoS attack. It’s whether your infrastructure is built to withstand one – without disruption.
Because in today’s landscape, downtime isn’t just an inconvenience – it’s an expectation that attackers are counting on.
