GitHub, a web-based code distribution and version control service, survived a massive denial of service attack on Wednesday. According to a report at Wired, a staggering 1.35 terabits per second (Tbps) of traffic hit the site at once. Within 10 minutes the company called for help from a DDoS mitigation service similar to Google's Project Shield, Akamai's Prolexic, which took over to filter and weed out malicious traffic packets. The attack, says Wired, ended after eight minutes. This may have been the largest DDoS attack ever; Wired notes the attack on domain name server Dyn in late 2016 reached 1.2 Tbps of traffic.
