A widespread internet outage has impacted numerous major websites and services worldwide due to a problem with Cloudflare, a leading internet security and infrastructure provider. The disruption affects popular platforms such as X (formerly Twitter), ChatGPT, OpenAI, Canva, League of Legends, and data services like DataWrapper. The outage began shortly after noon, with over 5,000 reports of issues on allestörungen.de, although the site itself was temporarily inaccessible. Cloudflare confirmed it was aware of the problem, which potentially affected multiple customers, and was working to understand and resolve it. As of 1:21 PM German time, the company reported signs of service recovery but warned of ongoing high error rates. Cloudflare's services are used by about 20% of all websites, meaning the impact is significant. The outage also affected user logins on platforms like BILD.de. The cause of the problem has not yet been disclosed, but the incident underscores the critical role Cloudflare plays in internet infrastructure and security.
