Changes to Routing Rules UX

We will soon be rolling out a series of UX and ARM API changes that will alter the behavior of routing rules for testing in production. After May 22nd, you will no longer be able to create routing rules in staging slots from the Portal, and on August 21st we will remove routing rules from all non-production slots. You will still be able to route traffic from your production slot to your staging slots to do testing in production. Please follow the instructions below to remove the routing rules from your staging slots.

The change

We originally allowed traffic routing from staging slots to enable advanced testing scenarios. However, we later learned that our customers were often routing traffic incorrectly and running into circular routing loops and other problems. Testing in production quickly gets complicated when routing rules are applied to non-production slots.

On August 21st we will remove all routing rules from staging slots. Rules on your production slot will not be changed.
