Services Internet et applications en panne suite à une défaillance majeure de Cloudflare
Une onde de choc traverse le web mondial ce 18 novembre 2025.
Cloudflare, l'infrastructure critique qui sécurise près de 20% d'Internet, subit une panne systémique majeure - faisant vaciller des milliers de plateformes simultanément.
Services financiers paralysés
Les échanges cryptos, applications bancaires et portefeuilles numériques sont parmi les premiers impactés. Les traders regardent impuissants leurs positions gelées tandis que les validateurs de blockchain tentent de maintenir la stabilité des réseaux.
Résilience décentralisée mise à l'épreuve
Ironiquement, cette défaillance d'un acteur centralisé survient alors que l'écosystème crypto prône la décentralisation depuis des années. Les nodes indépendants continuent de fonctionner, mais les interfaces utilisateurs reliant le grand public aux blockchains sont coupées.
Une piqûre de rappel coûteuse pour l'industrie - parce que même dans la finance nouvelle génération, mettre tous ses œufs dans le même panier cloud reste une stratégie risquée.
Tracking outages across major platforms caused by Cloudflare
The platforms hit were big names. PEOPLE on X complained they could not refresh posts. Gamers trying to play League of Legends or Valorant saw reports pile up on downdetector.
Even the Cloudflare status page itself began breaking down around 7:03 AM ET, losing its CSS styling while the company said its team was “continuing to investigate this issue.”
The official wording earlier at 6:48 AM ET said the company was aware of a problem that “potentially impacts multiple customers” and that more information would come later.
Users trying to work found themselves blocked from random corners of the internet. Anyone loading Canva ran into problems creating or saving content. People trying to access OpenAI bumped into messages telling them to “Please unblock challenges.cloudflare.com to proceed,” which also stopped access to ChatGPT.
That message spread across many websites at once because the security layers Cloudflare normally uses to protect them were not working, even though the websites behind them stayed online.
People online tried to figure out if the error screens meant they were blocked. They were not. The Cloudflare tools that usually filter traffic were the part breaking, not the users. The outage came fast, broke things fast, and hit global platforms at the same time, which is why the impact felt huge.
