At the same time, Cloudflare denied rumors that the problem arose as a result of an attack. But because of an error in the configuration of its servers. Note that the system shutdown itself lasted 27 minutes and traffic fell by 50%. But not the entire Cloudflare network was affected, but only some regions. The affected regions include London, Amsterdam, Frankfurt, Paris, Stockholm, São Paulo, Sao Paulo, Curitiba, Porto Alegre, Dallas, Seattle, Los Angeles, Chicago, Washington, Richmond, Newark, Atlanta, Moscow and St. Petersburg.
