Cloudflare, Inc. is an American web-infrastructure and website-security company, providing content-delivery-network services, DDoS mitigation, Internet security, and distributed domain-name-server services. Cloudflare's services sit between a website's visitor and the Cloudflare user's hosting provider, acting as a reverse proxy for websites. Cloudflare's headquarters are in San Francisco, California, with additional offices in Lisbon, London, Singapore, Munich, San Jose, Champaign, Illinois, Austin, New York City and Washington, D.C. Cloudflare has faced several controversies over its stance on providing technical support to online hate groups and terrorists—support it has defended based on the principle of free speech. Cloudflare stated that it will "continue to abide by the law" and "serve all customers", further explaining "our proper role is not that of Internet censor". These controversies have involved Cloudflare's service of The Daily Stormer, a neo-Nazi, white supremacist, and Holocaust denial commentary and message board website; and 8chan, an imageboard which has been linked to multiple mass shootings in the United States and the Christchurch mosque shootings in New Zealand. In 2017, Cloudflare decided to cease providing services to The Daily Stormer. In August 2019, Cloudflare stopped services for 8chan following a mass shooting in El Paso stating that 8chan is "refusing to moderate their hate-filled community". In 2014, Cloudflare introduced an effort called Project Galileo in response to cyberattacks against vulnerable online targets, such as artists, activists, journalists, and human rights groups. Project Galileo provides such groups with free services to protect their websites. In 2019, Cloudflare announced that 600 users and organizations were participating in the project.
