Cloudflare

The company is notable because its services underpin a significant portion of the modern internet. By acting as a reverse proxy and security provider for millions of websites, it plays a critical role in mitigating cyberattacks, such as DDoS attempts, and in accelerating web traffic globally. Its extensive reach makes it a fundamental piece of infrastructure for a diverse array of online platforms.

Cloudflare has recently been in the news due to a major service outage. In late 2025, a widespread disruption to its network caused numerous popular websites and services, including ChatGPT and X, to become inaccessible for a period of time. The incident highlighted the company's central role in the internet's ecosystem.

According to news reports, the company worked to restore services and subsequently identified the root cause of the hours-long outage. The disruption was widely covered by international media, underscoring how a technical failure at a single infrastructure provider can have a cascading effect on a global scale. The company issued an apology and provided a technical explanation for the event.
