Cloudflare, a key internet infrastructure provider, has experienced outages that affected large parts of the internet. According to reports<\/a>, the most recent outage occurred on December 5, 2025, due to internal service degradation during scheduled maintenance at the Detroit data center.<\/p>\n The causes of these outages vary, but they often result from internal configuration issues or technical failures. For instance, the November 18, 2025, outage was caused by a misconfigured database permission that allowed a Bot Management feature file to grow uncontrollably large, overwhelming Cloudflare\u2019s routing and proxy systems. This incident affected core services like DNS, CDN delivery, and web access for thousands of businesses worldwide, as explained in Cloudflare’s blog post<\/a> on the incident.<\/p>\n These outages have significant implications for businesses and users. As noted by Forbes<\/a>, the outages affect not only Cloudflare’s customers but also the broader internet ecosystem, highlighting the centralized risk associated with relying on a few large providers.
