Downtime, timeouts or slow responses are simply unacceptable. The idea is not to simply offer a public CDN, but to offer the best possible experience and a rock-solid product. We have multiple layers of failover on different levels. Read about in detail Multi-CDN Load balancing.
According to Cedexis Radar, jsDelivr has the highest uptime across ALL enterprise CDNs including Akamai, CloudFront and Edgecast.
Multi-CDN load balancing, smart algorithm, real time data, real user metrics and multiple CDN providers all come together to ensure the best possible performance for all users.
Our project is open source and "not for profit". Everything we do, we do it for the community and a better web. We are focused to help all developers and website owners. And thanks to our open design we will never be vendor-locked to a single provider or technology, this means that no company can influence the project in a hurtful way as we can simply move away.
All jsDelivr related accounts are protected using 2-step authentication and IP whitelists by services that support them, along with a strong password. The origin server is accessible only from a few whitelisted IPs used by a single admin and a Github deployment service. All precautions are taken to protect our users.
