How to make sure your website is resilient in 2026

In recent years, several major incidents at leading CDN providers have caused service outages lasting several hours. Meanwhile, DDoS attack volumes are reaching record levels, with the trend continuing to rise.

A CDN (Content Delivery Network) distributes your content (web pages, videos, APIs) as close as possible to your end users, reducing latency and ensuring availability.

The Multi-CDN approach goes further: it involves using multiple CDN providers in parallel and intelligently distributing traffic between them in real time. Rather than relying on a single provider, you diversify your network to maximize the performance, resilience, and flexibility of your digital content delivery.

What Multi-CDN delivers

Geographic performance. Routing each user to the fastest CDN at any given moment, from their network zone, typically results in a 15 to 30% improvement in your LCP (Largest Contentful Paint) score. This has a direct impact on conversion rates and Core Web Vitals.

Compliance and resilience. Recent European regulations (DORA for finance, NIS2 for critical infrastructure) and data protection requirements such as Schrems II encourage organizations not to depend on a single provider. Multi-CDN is no longer just a technical option, it is a compliance requirement. You demonstrate that your service remains available and compliant even if your primary provider suffers an outage or a legal restriction.

This is Optimi's core expertise. We select the best providers based on the specific needs of each client. By ensuring this technical governance, we secure your revenue and brand image while freeing you from the complexities of managing multiple vendors.

Why does it matter?

For an e-commerce site generating €50M per year, a simple two-hour outage represents a direct revenue loss of up to €15,000.

Beyond this immediate cost, it is your brand image and contractual commitments (SLAs) that are put at risk.

Our vendor-agnostic approach allows us to combine the best infrastructures on the market based on each client's profile, and our expertise enables fine-tuned configuration and continuous real-time performance monitoring of your traffic flows.
