On November 18, 2025, the internet faced a significant disruption as Cloudflare, a crucial internet infrastructure provider, experienced a massive outage impacting thousands of websites worldwide. Leading platforms such as X (formerly Twitter) and the AI powered ChatGPT saw service interruptions, highlighting the dependency of the modern web on Cloudflare’s network.
Cloudflare attributed the outage to an unexpected and “unusual traffic spike” that began around 11:20 UTC, overwhelming its systems and causing widespread HTTP 500 server errors. This incident resulted in millions of users encountering inaccessible websites and interrupted online services globally.
Notably, two major services reliant on Cloudflare, X and OpenAI’s ChatGPT, were particularly affected, leaving users unable to access these platforms for several hours. The popular outage monitoring site Downdetector also suffered the impact, underscoring the outage’s scale.
Cloudflare’s engineering team responded swiftly, restoring most services within a short period. Investigation is ongoing to determine the definitive cause of the traffic surge, with Cloudflare committed to a transparent post incident analysis.
This outage serves as a stark reminder of the pivotal role internet infrastructure providers play in maintaining the seamless functioning of online ecosystems. As digital platforms continue to grow and integrate globally, resilience against such large scale disruptions becomes ever more critical.
