Internet Outage

On November 18, 2025, Cloudflare, a key internet infrastructure and cybersecurity firm, experienced a significant service outage, disrupting numerous websites globally. The disruption, traced to an oversized automatically generated configuration file, impacted platforms like Shopify, Indeed, and even Downdetector. While most services were restored within hours, the incident highlighted the reliance on intermediary services and the potential for cascading failures. The outage, which followed recent disruptions at AWS and Azure, underscores the vulnerability of concentrated internet infrastructure and raised questions about Cloudflare’s long-term stability, causing its stock to dip.
