And all blue-green-deployment-scripts which I've seen so far have this issue. Best regards Jens From: Considering the routing tier is horizontally scalable, what would your success criteria be for "a route is mapped to an app"? But not sure if I got you wrong. Even when waiting for 5 minutes, it could be we get ajust because the response came from the old version, so we think it works, but when we now disconnect the old version it'd be fatal. Changes to docs have been committed, and will show up with the next push of the docs app. I'll submit a PR to update the docs now. Yes, or check that the new version of your app is responding before unmapping the old version from the route. Regarding your proposal of exposing a version endpoint, I do think this is a workaround that could help in most scenarios. See also the next comment below.

Some of the issues could be fixed by repeatedly pinging the application in order to wait until the route has been mapped.
Given we have a lot of instances of the old version, and just created one or a few instances of the new version on the same route - how do we even know that the route mapping worked at all? So, is the route mapping really supposed to be asynchronous? In our internal discussion with our CF operators, we found a couple of parts of documentation which at least hint to different, maybe even inconsistent inner workings of the route mapping: Hello Thomas, Comments inline.
There isn't a simple solution at the moment but I have recorded your feedback.

|The routing table is indeed updated asynchronously, and we can update the docs to clarify this; "immediately" may be a bit misleading.
Maybe expose a version endpoint? For quite some time we have discussed offering automated cutover between versions of an app as a built-in feature, so app developers wouldn't have to use these blue-green scripts. We are aware that there is more CF could do with regard to upgrading apps without downtime. I understand your concern.

On Tue, Feb 7, at 2: I'm not aware what would happen if only some percentage of the routers had the routing tables updated; if that means that a few requests would reach the new version, giving one the impression that the mapping was successful and one could disconnect the old app, then this would be an issue. But what about blue-green-deployment, where I map the application to a route on which there is already a running application.
