GitHub is the world's largest source code hosting platform and developer community, founded in 2008 and acquired by Microsoft in 2018 for $7.5 billion. With over 100 million developers and 400 million repositories, GitHub has become the central hub for open-source development and enterprise software collaboration.

The platform pioneered social coding features like pull requests, issues, and forking that have become industry standards. GitHub hosts the source code for countless major projects including Linux, React, TensorFlow, and VS Code. The company also provides GitHub Actions for CI/CD, GitHub Pages for static hosting, Copilot for AI-assisted coding, and comprehensive security scanning.

GitHub's infrastructure runs on Microsoft Azure, having migrated from its original Rackspace-based setup. The platform uses a globally distributed architecture with multiple data centers for redundancy. GitHub experienced a famous 2018 DDoS attack that peaked at 1.35 Tbps, the largest recorded at that time, which they mitigated using Akamai Prolexic.

DNS for github.com is managed through multiple providers for resilience, with authoritative nameservers including dns1-4.p08.nsone.net (NS1). The site uses advanced DNS configurations including DNSSEC and CAA records for certificate authority authorization. GitHub's global CDN delivers assets from edge locations worldwide for optimal performance.
