We are using Suse SLES 12 images on Azure in our deployments, out of the East US region. The images are of Suse SLES 12 SP1, created from official suse images.
When we ran zypper to search or check the status of a package, zypper simply hangs.
Annoyingly, it also deletes all repositories from /etc/zypp/repos.d after such failures.
Trying to re-register the VM (using /usr/sbin/registercloudguest) hangs as well.
PS: The issue (or others, similar) keeps happening every few days with zypper azure repository..
