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.
