Last night, GitHub was hit with massive denial-of-service attack from China
Last night, GitHub was hit with a massive denial of service attack, directed by the Chinese internet giant Baidu. Some time Wednesday, Baidu scripts throughout the web began directing traffic to two specific GitHub pages: one run by GreatFire, and another mirroring Chinese translations of The New York Times. The result for Github was a massive flood of traffic, which built for more than 24 hours before causing partial outages Thursday night. The site is now fully recovered, although according to admins, the attack is still ongoing.
