A Decade of Scalable, Secure Protection: Python Software Foundation + Fastly Empower the Community

Through a decade-long partnership with Fastly, Python Software Foundation (PSF) & Python Package Index (PyPI) sustains around 100,000 requests per second with a 98–99% cache hit rate—reducing backend traffic to just 500–1,000 requests per second—while delivering real-time content updates within milliseconds. This high-performance, secure infrastructure enables the small PSF team to defend against account abuse, bots, and supply chain threats, maintain reliable open access for millions of developers, and avoid significant backend scaling costs.
