How to implement a multi-CDN strategy

Re:How to implement a multi-CDN strategy by mahesh_rm on Wednesday November 07, 2018 @01:26PM (#18401053)

Using this comment thread to plug a question: Is there a way to use Cloudflare (or other DNS server providers) in order to dynamically fallback to CDN A (e.g. Cloudfront) in case CDN B (e.g. Netlify CDN) is down?

I don't think Cloudflare Load Balancing can do this (yet), but Dyn can: https://dyn.com/active-failover/

The crucial part is CNAME compatibility. Most DNS services I've had experience with can only do failover between IPs.

You can control DNS failover with custom health checks in AWS Route 53. You can also do latency based routing. I can't speak for Cloudflare, but I imagine they have similar capability.

Thank you. I overall prefer CF over R53, will try to check out if this can be achieved with either workers or page rules.

I work for a startup called DLVR (Deliver) and we do this for video streams. HLS, DASH, MSS http://www.dlvr.com

Pretty sure Netlify's CDN is Akamai. So top tier for sure.
