Success at scale: Preparing Drupal 8 for large events

on YouTube ↗53m

" summary

Drupal 8 site architecture handles 3.9 billion requests from 8.4 million unique visitors over 11 days by leaning on aggressive caching: Varnish + global CDN (Cloudflare) + Acquia Cloud, BLT and Lightning for consistent delivery, and a custom CloudFlare CLI to surface cache offenders. Practical fixes include hashing cache tags to avoid Cloudflare’s 255‑byte limit, using a 60s TTL at the edge, and blacklisting noisy tags to sustain a ~99.9% cache‑hit rate.
