Case Study: Previon Plus achieves high-traffic website reliability for Züri Fäscht with amazee.io

How to Prepare Your Website for High-Traffic Events

The customer, Previon Plus, partnered with vendor amazee.io and its hosting platform to prepare the website for Züri Fäscht, Switzerland's largest festival, for a massive surge of traffic from two million visitors. The challenge was to ensure optimal user experience, site performance, and total reliability during this high-traffic event, requiring the site to handle thousands of simultaneous users without failure.

The solution from amazee.io involved a meticulous, months-long collaboration focusing on the Drupal application and, crucially, the Content Delivery Network (CDN) configuration. By optimizing caching modules and fine-tuning the Fastly CDN service, amazee.io achieved exceptional results: the site successfully withstood a pre-event attack of 1.4 million hits in 40 seconds and during the festival maintained a 96.64% CDN hit ratio and over 99% cache coverage, ensuring minimal load on the infrastructure and a seamless experience for all visitors.
