Case Study: Catch Digital achieves 25× traffic handling and 98–99% cache hit rates with Fastly

Catch Digital - Customer Case Study

Catch Digital is a full‑service digital agency (London & New York) that builds Drupal sites and runs ecommerce and promotional campaigns for clients like Rimmel and One Direction Fragrances. For the One Direction launch they needed a CDN that gave them granular control over caching (including excluding shopping baskets), easy Drupal integration, and the ability to test changes safely across production and development environments.

They used Fastly, built on Varnish, to implement custom VCL rules and the Fastly/Drupal module (including session‑cookie logic to prevent caching baskets), preview changes on separate services, and instantly purge content. The result: the site absorbed a 25× traffic spike with 98–99% cache hit ratios, fewer origin servers, lower costs, and much faster, globally distributed performance for millions of fans.
