Case Study: Earth Hour achieves 35% hosting cost savings and a scalable, high-performance Drupal platform with Acquia

Earth Hour 60 Minutes, 154 Countries and Territories, One Uniting Website

Earth Hour, the World Wide Fund for Nature’s global grassroots campaign, uses earthhour.org to unite millions for an annual "lights out" climate action and year‑round initiatives. With a lean core team, hundreds of volunteers worldwide, an open‑source brand model and peak traffic of 3–4 million hits during the event, the organisation needed a more manageable, optimised web platform, formal SLAs and a cost‑effective digital strategy to replace disparate point solutions.

Earth Hour migrated its Drupal site to Acquia Cloud, gaining an agile, scalable and secure hosting platform plus ongoing services like monitoring, updates, load balancing and strategic support. The move delivered significant benefits: about 35% annual hosting cost savings, stronger operational resilience and confirmation that roughly 20% of traffic is mobile—informing a multichannel user‑experience strategy going forward.
