Architecting a live look at reliability: Stripe's viral Black Friday site | Customers | Vercel

This post details how Stripe built and optimized a real-time microsite to showcase their Black Friday Cyber Monday (BFCM) reliability. Key technical contributions include: architecting a live look at core business metrics, handling 17M+ edge requests at launch with 100% uptime, utilizing Vercel's framework-defined infrastructure to focus on design and reliability rather than cache system architecture, and implementing a strategy combining getStaticProps, Stale-While-Revalidate (SWR) for client-side real-time data and background revalidation, and Incremental Static Regeneration (ISR) with a one-second max-age cache for efficient background data generation and reduced backend load. The post also highlights Stripe's focus on isolation of the microsite's data sources from core infrastructure and a fallback strategy for metric updates.
