I am looking forward to that! Linode is my go-to hosting service, but it's a little troubling that anyone in the datacenter can hit your private IPs [1]. On the other hand, maybe it shouldn't matter, and you should always act like the network is compromised. Isn't trusting their private network how Google leaked traffic to the NSA? Still, it seems like a nice improvement that would make compromises less likely.
