A familiar debate is once again surrounding Cloudflare, the content delivery network that provides a free service that protects websites from being taken down in denial-of-service attacks by masking their hosts: Is Cloudflare a bastion of free speech or an enabler of spam, malware delivery, harassment and the very DDoS attacks it claims to block?
The controversy isn't new for Cloudflare, a network operator that has often taken a hands-off approach to moderating the enormous amount of traffic flowing through its infrastructure. With Cloudflare helping deliver 16 percent of global Internet traffic, processing 57 million web requests per second, and serving anywhere from 7.6 million to 15.7 million active websites, the decision to serve just about any actor, regardless of their behavior, has been the subject of intense disagreement, with many advocates of free speech and Internet neutrality applauding it and people fighting crime and harassment online regarding it as a pariah.
Spamhaus—a nonprofit organization that provides intelligence and blocklists to stem the spread of spam, phishing, malware, and botnets—has become the latest to criticize Cloudflare. On Tuesday, the project said Cloudflare provides services for 10 percent of the domains listed in its domain block list and, to date, serves sites that are the subject of more than 1,200 unresolved complaints regarding abuse.
