Authentication/trust is simply unrelated to this outage. The post you linked seems to have no relevance.

One of Cloudflare's top engineers previously wrote in this forum,

> This incident emphasizes the importance of the Zero Trust model that Cloudflare follows and provides to customers, which ensures that if any one system or vendor is compromised, it does not compromise the entire organization. [1]

Authentication is a part of a zero-trust model, not the whole thing.

> No single specific technology is associated with zero trust architecture; it is a holistic approach to network security that incorporates several different principles and technologies. [2]

They were referring to a completely different incident, involving compromised authentication to a camera system. I’d love to hear an explanation of how a zero-trust model would apply to this situation with Fastly. Seems like it would have to apply to a lot of multi-tenant resource exhaustion issues since we know so little about the specifics on the Fastly incident.

A blog post concerning how customer configurations cannot bring down other customers' sites would be great to see from Cloudflare. Fastly does not seem in a position to say that about its own stack and I don't expect another company to know their stack that well.
