Now you have to wait for resiliency to replace your master. The original kvm0 (or runner0) will be rename to "broken" and the kvm1 (or runner1) will be renamed to kvm0 and a new clone will be requested. Once the process is over, the system will be readjusted and your access will be moved to the new master.
Since your services changed the computer where they run on, they changed their IPv6.
If you have a webrunner, you should redeploy your services inside the webrunner so that they know about the change. Also, you will need to change all the frontends pointing to your services (especially, the custom frontend if you have one).
If you have a KVM, you may need to update the IPv6 inside your machine if you used IPv6 provided by Rapid.Space.
