These CDN providers often offer integrated DNS services as part of their package. By leveraging these services, Facebook can benefit from the expertise and infrastructure of these specialized providers without having to manage their own DNS server.

This allows them to focus on what they do best – connecting people and providing an exceptional user experience.
