Modernising Global Multi-Site Infrastructure at Scale for Hillsong Church

Hillsong Church partnered with 4mation to rebuild and modernise its global website infrastructure.

With operations across 28+ cities and a weekly global attendance of approximately 150,000 people, Hillsong required a secure, scalable, multi-site digital platform capable of supporting regional autonomy, multiple languages, and high daily traffic volumes. 4mation delivered a new AWS-backed multi-site WordPress architecture, migrating over 50,000 pages of content while improving performance, stability, and editorial experience.

The result was a faster, more secure global website positioned for long-term growth.
