OVHcloud, Europe's largest cloud provider, offers a CDN alongside its hosting and famously robust anti-DDoS protection, which is included across its infrastructure at no extra cost. From its French base it runs its own global network and data centres, giving customers real European data sovereignty.
If you already value OVHcloud's independence and its industry-leading DDoS mitigation, its CDN is a natural, sovereignty-friendly step away from Cloudflare.
