A blog post by Matthew Prince, Cloudflare's CEO, suggests that Cloudflare repeated CrowdStrike's mistake: updating the entire infrastructure without first testing on a small group of hosts. As a result, large portions of the internet, including 4sysops, were inaccessible for several hours. Apologies for the latter. While most news sites reported that 20% of internet traffic was affected, the actual impact was much higher because the outage disproportionately affected high-traffic, top-ranking websites like X, ChatGPT, Perplexity, and Spotify. While Cloudflare's CEO blames a manual database permissions change, the incident exposes a deeper design flaw: a single engineer can disrupt massive portions of global internet infrastructure. In contrast, blockchain networks like Ethereum demonstrate how truly decentralized systems can prevent such single points of failure.

Windows 10 devices enrolled in Extended Security Updates may experience installation failures when attempting to install the November 2025 security update (KB5068781). There were some problems installing updates, but we'll try again later. "Error encountered: If you keep seeing this and want to search the web or contact support for information, this may help: (0x800f0922)." The issue affects a specific subset of commercial customers using cloud-based licensing activation. This ESU issue appears to be unrelated to the error, 'We can't enroll you in Extended Security Updates right now,' because the enrollment error prevents access to ESU updates, while the current issue affects installation on devices that are already enrolled. Microsoft now released the KB5072653 update to fix the 0x800f0922 error.

However, the response from the tech community has been overwhelmingly negative, forcing Microsoft to address concerns about the platform's direction. The backlash has brought AI skeptics and change-resistant IT professionals into the open.
