Having trouble trying to access GitHub, a website known for hosting and sharing programming code and other specialized content? The site is facing a major distributed denial-of-service (DDoS) attack that started on Thursday and has continued to evolve and pose problems throughout the weekend.
The site seems to be working better now, but the company has confirmed problems starting on Thursday - and continuing until early afternoon on the east coast: "87 hours in, our mitigation is deflecting most attack traffic," GitHub said in a public post. "We're aware of intermittent issues and continue to adapt our response."
It's unknown what perpetrators are behind the attack, but it appears a reflection attack - which pulls traffic from other sites to overwhelm GitHub's server - could be to blame, according to Arbor Networks.
"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," according to a GitHub blog post. "Based on reports we've received, we believe the intent of this attack is to convince us to remove a specific class of content."
