GreatFire (GreatFire.org; Chinese大火) is a non-profit organization that monitors the status of websites censored by the Great Firewall of China[3] and helps Chinese Internet users circumvent the censorship and blockage of websites in China.[4][5] The website also hosts a testing system that allowed visitors to test in real time the accessibility of a website from various locations within China. The organization's stated mission was to "bring transparency to the Great Firewall of China."[6]

GreatFire has worked with BBC to make the Chinese-language BBC website available to users in China, despite it being blocked by the Great Firewall, by using a method known as collateral freedom[7] that mirrored content on widely used content delivery networks, such as Amazon CloudFront and CloudFlare, so that it would be too economically costly for censors to block.[8][9][10] The organization has since set up similar mirror sites for other blocked websites, such as Google and the New York Times, with a directory of links hosted on GitHub, which is currently not accessible in China.[11]

GreatFire has been targeted with distributed denial-of-service attacks that attempt to take down the website by overloading its servers with traffic.[12] In April 2015 it was targeted by a Chinese attack tool named Great Cannon that redirected massive amounts of Internet traffic to servers used by GreatFire.[13]

A sister site FreeWeiboChinese自由微博) monitors and makes available content from leading Chinese microblogging site Sina Weibo that has been censored and deleted by Chinese authorities under the Great Firewall.[14]
