When will IP Sharing be available in Sydney?

I just noticed that IP Sharing isn't available in Sydney!

I am planning a 2 node cluster (I know, not a good idea, but better than 1). For which I need VLAN and IP Sharing (in case one server goes down, the passive server can act as the active one).

My product development is still going on, so I am not really ready to set up the cluster, yet. But I would like to see an expected timeline on when IP sharing will be available in Sydney.
