Multi-cluster fallback/failover

[kickthemooon]

There are two clusters.
There are two services/applications.
All public requests first go to a primary app in one cluster.
If the primary app knows the request (non 404 http response code) it responds appropriately.
If the primary app doesn't know the request (404 http response code) it redirects the request the fallback secondary app running on another cluster.

Question is, is linkerd the way to go here and can this scenario be implemented with linkerd?

Linkerd doesn't support this today. You could configure Linkerd to retry requests that get a 404 response, but we can't guarantee that the retried request won't go to the primary service.
