Brotli is a modern compression algorithm competing to replace gzip as the compression algorithm for the web, improving compression rates by up to 20%, and speeding up the delivery of your sites. Brotli is widely supported by browsers and will be enabled by default on all new servers and sites created via SpinupWP.

SpinupWP customers will notice a mandatory upgrade in their dashboards for all servers running Ubuntu 22.04 LTS and 24.04 LTS. This upgrade is not available for servers running older versions of Ubuntu. When you run this upgrade, the Brotli compression module for Nginx will be installed on the server and the Nginx configuration files will be updated to enable it.

If you’re wondering why you need to manually upgrade each server and why we don’t just force upgrade all servers, please read our manifesto here.
