Comment 6 for bug 1578906

This issue is resolved, but I am concerned this issue can happen again.

1. Canonical, and specifically CPC does not provide official Ubuntu images to rackspace. You wont find rackspace in image streams at cloud-images.ubuntu.com.

2. Martin generated streams to test the the rackspace provder works. These streams have become the defacto official streams. see
   https://jujucharms.com/docs/master/help-rackspace

3. Both CPC and Juju QA share the account to test in rackspace. The rackspace streams are just files in swift under the shared account.

4. There was a cleanup of resources in that account a just prior to the outage. Someone not realising the swift container serves images streams deleted it.

The images streams were republished. It took just a few minutes.

Until CPC provides official images and streams, we need to safeguard the streams in the shared account.

1. The cloud health check was successful in identifying the issue. Now that we understand it, it is easy to take immediate action to republish streams to the swift container.

2. We cannot lock the container. So the CPC and juju QA team need to know NEVER delete juju-ci-image-streams container or its objects.
