Summary

On February 28, 2018, GitHub.com experienced a temporary outage due to a distributed denial-of-service (DDoS) attack that exploited a vulnerability in memcached instances accessible over the internet, resulting in an unprecedented amplification factor of up to 51,000 times. The attack, which peaked at 1.35Tbps, was mitigated by GitHub's network monitoring system that detected an anomaly and shifted traffic to Akamai for additional edge network capacity, effectively resolving the issue within minutes. GitHub emphasizes its commitment to enhancing its infrastructure's resilience by expanding transit capacity, developing automated intervention strategies, and working with partners to block and filter such attacks. The company is focused on improving its response times and is committed to continuously analyzing incidents to better protect its users' workflows and projects.
