Coding website GitHub has been hammered by an ongoing denial of service attack that, reportedly, has ties to China.
The cyber-attack, the largest in its history, began last Thursday and was still active Sunday night, although GitHub did say it had the situation under control.
“All systems reporting at 100 percent. Attack traffic continues, so we remain on high alert,” the Web-based hosting service said in a tweet.
87 hours in, our mitigation is deflecting most attack traffic. We’re aware of intermittent issues and continue to adapt our response.

The Wall Street Journal is reporting the torrent of Internet traffic came via Baidu, a Chinese search engine. The attack apparently targeted two GitHub pages linking to copies of sites currently banned in China.
“The attack … involves a wide combination of attack vectors,” GitHub said in a blog post. “These include every vector we’ve seen in previous attacks as well as some sophisticated new techniques that use the Web browsers of unsuspecting, uninvolved people to flood github.com with high levels of traffic. Based on reports we’ve received, we believe the intent of this attack is to convince us to remove a specific class of content.”
Despite being under fire for more than four days, GitHub said it would not back down.
“We are completely focused on mitigating this attack,” the company said.” Our top priority is making sure github.com is available to all our users while deflecting malicious traffic.”
