CDN Switching Blind Spots Can Result in Rebuffering

Reducing video rebuffering can be difficult. Going multi-CDN can provide several benefits for customers, such as better geographic coverage and, possibly, better economics. Adding live switching logic between the CDNs goes a step further and enables load balancing and redundancy in case of problems. Different layers of redundancy and different levels of granularity try to address the various outages an online delivery pipeline might experience. A combination of several such redundancy tools is likely to achieve the best UX.
