Cloudflare Outage: Global Disruption Takes Crypto Sites Offline

A widespread outage at Cloudflare disrupted various internet services on November 18, 2025, significantly affecting numerous cryptocurrency platforms. Major sites like Arbiscan and DefiLlama experienced downtime, alongside the social media platform X, showing internal server errors. The issue was attributed to Cloudflare's system-wide disruption, which led to widespread '500' errors and failures across its dashboard and API. Cryptocurrencies traded on exchanges such as BitMEX also reported related outages. Following the event, shares of Cloudflare Inc (NET) dropped by 3.5% in pre-market trading, as the company worked to investigate and address the service failures. This incident highlights the dependency of many blockchain-related services on third-party service providers like Cloudflare, raising concerns among users regarding the stability and reliability of online crypto services.
