# Content Delivery Network

Accelerate your websites and applications with Edge Network's global CDN. Automatic SSL, intelligent caching and real-time image optimisation.

## Key features

- **Global edge network:** content served from edge locations worldwide for <15ms response times.
- **Automatic SSL:** free Let's Encrypt certificates issued automatically for all domains.
- **Smart image optimisation:** on-the-fly resizing with automatic format detection (AVIF, WebP or JPEG, based on the browser).
- **Presets and custom rules:** start with optimised presets or define custom caching and image rules per path.
- **Instant purging:** clear cached content globally in under 200ms.
- **Real-time analytics:** monitor requests, bandwidth and cache hit rates, identify top content, and track all changes with the activity log.
