Global Tech Outages: The Need for Resilience for Internet Connectivity
In today’s hyper-connected world, reliable internet connectivity is the backbone of almost every sector. From businesses and healthcare to education and entertainment, uninterrupted internet service is crucial. However, recent global tech outages, such as the one that occurred in July 2024, have underscored the pressing need for enhanced resilience in our internet infrastructure.
In July 2024, a major outage was triggered by a faulty software update from CrowdStrike, affecting millions of Windows devices globally. The issue stemmed from a defect in a “content update” for CrowdStrike’s Falcon Sensor, which led to widespread Windows’ Blue Screen of Death (BSOD) errors. This disruption impacted various sectors including airlines, banks, media outlets, and public services, grounding flights, disrupting financial transactions, and hindering news broadcasts.
CrowdStrike CEO George Kurtz confirmed that the outage was due to a technical fault and not a cyberattack. A fix was quickly deployed, but the resolution required manual intervention on affected systems, adding to the complexity and duration of the disruption. This incident underscores the critical importance of rigorous testing and validation procedures for software updates to prevent such large-scale impacts in the future.
This article delves into what is resilience in internet connectivity, how to build a robust and resilient internet connectivity framework, and the symptoms of a failing internet infrastructure during outages.
Why did the July 2024 CrowdStrike incident affect only Windows computers?
The CrowdStrike incident affected only Windows systems because the defective update targeted Windows hosts specifically, causing critical errors in the operating system’s kernel during boot time. This led to widespread Blue Screen of Death (BSOD) errors, a type of crash unique to Windows environments.
In contrast, Linux systems are better protected against kernel failures at boot time due to several mechanisms. Firstly, Linux typically maintains multiple kernel versions on the system. If a newly updated kernel fails to boot, the system can fall back to a previous stable version. Additionally, Linux bootloaders like GRUB (GRand Unified Bootloader) allow users to select different kernels or recovery modes manually, providing a more robust recovery process in case of critical failures. Moreover, the modular architecture of Linux kernels means that even if a kernel module fails, it often doesn’t render the entire system unbootable, as modules can be loaded or unloaded dynamically without requiring a reboot.

Understanding What is a Global Tech Outage
A global tech outage refers to a widespread disruption in internet services, affecting multiple platforms and services simultaneously. These outages can have far-reaching effects, crippling business operations, halting financial transactions, disrupting communication channels, and posing risks to public safety. For instance, the 2024 outage impacted numerous tech giants, causing significant disruptions across various sectors and highlighting our dependence on these platforms.

What is Resilience in Internet Connectivity?
Defining What is Resilience in Internet Connectivity
Resilience in internet connectivity refers to the network’s ability to withstand and quickly recover from disruptions. This involves having redundant systems, robust cybersecurity measures, and effective response strategies in place. Enhancing resilience ensures that even if one part of the network fails, the overall system remains functional, minimizing downtime and maintaining service continuity.
How to Enhance Internet Resilience
Implementing Redundant Systems
Wondering how to implement redundant systems? One of the most effective ways to build resilience is through redundancy. This involves having multiple pathways for data to travel. If one route fails, data can be rerouted through an alternative path, ensuring continuous connectivity. Data centres and ISPs (Internet Service Providers) should invest in redundant network infrastructure to mitigate the risk of outages.
How to Establish Robust Cybersecurity Measures
Cyberattacks are a significant cause of tech outages. How to protect against these threats? Implement robust cybersecurity measures such as regular security audits, deploying firewalls, using encryption, and educating users about phishing and other cyber threats. A secure network is less likely to experience disruptions due to cyberattacks.
How to Develop Effective Incident Response Strategies
Having a well-defined incident response strategy is crucial. How to prepare for incidents effectively? Identify potential risks, develop response plans, and conduct regular drills to ensure readiness. An effective response can significantly reduce the impact of an outage, ensuring that services are restored swiftly.
Symptoms of a Failing Internet Infrastructure
Recognizing Symptoms of Internet Infrastructure Issues
Symptoms of a failing internet infrastructure can include frequent outages, slow data speeds, increased latency, and vulnerability to cyberattacks. These symptoms indicate that the current infrastructure lacks the resilience needed to support continuous and reliable connectivity.
The Role of WorldDirector in Ensuring Resilience
Leveraging WorldDirector for Enhanced Resilience

Its comprehensive suite of tools also includes real-time monitoring and automated failover mechanisms, making it an invaluable asset for businesses seeking to safeguard their internet connectivity against global tech disruptions.
Bridging the Knowledge Gap Among C-Level Executives
Addressing Tech Ignorance Among C-Level Executives Worldwide
A significant barrier to building resilient internet infrastructure is the knowledge gap among C-level executives worldwide. Many leaders lack a deep understanding of the technological foundations of their operations, which hampers effective decision-making and investment in critical areas like cybersecurity and redundancy. This tech ignorance is not limited to any specific country; it is a global issue that needs addressing. Bridging this knowledge gap is essential for the successful implementation of resilient systems. Educating executives on the importance of internet resilience and the technical aspects involved can lead to more informed strategies and investments.
The Role of Governments and Private Sector in Ensuring Resilience
Collaborative Efforts for a Resilient Internet
Building a resilient internet infrastructure requires collaboration between governments, private sector entities, and international organizations. Governments can enact policies and regulations that mandate resilience standards, while private companies can invest in the necessary technologies and infrastructure. International cooperation is also vital to address cross-border cyber threats and ensure global internet stability.
The Future of Internet Connectivity
As we continue to rely more heavily on the internet, the need for resilient connectivity becomes increasingly critical. By understanding what is resilience in internet connectivity, implementing redundant systems, establishing robust cybersecurity measures, and developing effective response strategies, we can build an internet infrastructure that can withstand disruptions and ensure continuous service. The recent global tech outages serve as a stark reminder of the importance of resilience, urging us to take proactive steps to safeguard our digital future.
By prioritizing resilience in internet connectivity and bridging the knowledge gap among C-level executives, we can create a more reliable and secure digital landscape, capable of supporting our increasingly connected world.
