What is a CDN and how does it work?
One CDN A Content Delivery Network (CDN) is a network of geographically distributed servers that delivers your website’s content from the closest point to the visitor. This reduces the distance data travels, decreases loading time, and, above all, reduces the energy consumption associated with each visit.
Instead of each user accessing the main server (for example, in Frankfurt), they access a temporary copy located in Paris, Madrid, or London. This way, unnecessary traffic is avoided, performance is improved, and environmental impact is reduced..
Sustainable advantages of using a CDN
Real energy savings
Serving less content directly from the origin server reduces the electrical load in data centers, which require constant cooling and consume a huge amount of energy. According to the European Environment Agency¹, the transmission and processing of data is one of the emerging sources of digital emissions.
Less network traffic, more efficiency
The use of a CDN avoids unnecessary intermediate hops between nodes and international routers. This reduces bandwidth usage on the internet backbone, which not only improves speed but also minimizes the energy used for each request.
Performance improvement, SEO, and user experience
A website that loads quickly not only improves conversion rates: it also reduces screen time, frustrating reloads, and battery consumption on mobile devices. The CDN positively impacts metrics like Core Web Vitals, and Google takes that into account.

What CDN do we use in Replanta?
At Replanta, we believe in Cloudflare, one of the most widespread CDN providers in the world. It stands out not only for its speed and security but also for its environmental commitment: since 2022, it has operated in a carbon-neutral manner and prioritizes nodes with improved energy efficiency through its initiative. Green Compute.
At Replanta, we believe in Cloudflareone of the most advanced and global CDN providers, with more than 300 distributed data centers strategically around the world. Thanks to its network of puntos de bordeEach request to your website is handled from the node closest to the visitor, drastically reducing latency, the energy consumption associated with data transport, and the carbon footprint.
Since 2022, Cloudflare operates in a carbon-neutral manner, and has launched its initiative Green Compute, which directs the traffic of non-urgent tasks (such as workers or edge functions) to data centers powered by renewable energy. This allows us to optimize efficiency without sacrificing performance, aligning with our mission to provide truly sustainable hosting.
Additionally, its edge infrastructure not only improves loading speed and security, but also minimizes indirect CO₂ emissions by avoiding unnecessary data transit between continents.
