Understand the benefits a move to a multi-CDN environment will
deliver to your business, your customers and the architectures involved.
A multi-CDN strategy allows a content provider to share traffic between two or more providers in order to mitigate the risks of issues with any individual provider. Whether it be micro outages, peak-hour performance degradation or other issues, having alternatives allows content providers to protect their end-users against user-experience impacts caused by a single CDN.
A second point to note is that during these events, CDN 2 was unaffected. This is not to suggest that CDN 2 is superior to CDN 1. Issues that occur on CDN 1 are not connected to issues that occur on CDN 2. If a customer had been able to quickly shift traffic from CDN 1 to CDN 2 during these occurrences, they would have been able to mitigate impact on end-user experience.
