Cloudflare had a contract with one of the largest illegal sites. It provided a content delivery network service, temporarily duplicating data from piracy site servers and distributing it to large numbers of users. Presiding Judge Aya Takahashi found that Cloudflare had simplified its identification procedure, enabling the piracy site operator, remaining anonymous, to efficiently distribute pirated copies. "[Cloudflare] failed in its duty to stop providing the service," the judge said, noting that the company did not suspend it even after the publishing houses had notified it of the copyright infringement. Cloudflare had argued that it was the website operator that transmitted the data and that it was unaware of the infringement.
