Some questions about Openspace sims...

I've been contemplating the addition of a set of Openspace sims to my estate for a while, and a couple questions have come up in my mind. Neither the knowledgebase or searching the forum availed me the answers, so I'm hoping someone might be able to sort this out for me.

I know that Openspace sims are four per CPU, and I know that when a (regular) sim crashes and reboots, it can move to a different CPU / server, based on what is in the queue of available servers / CPUs. What I would like to know is:

A) When you get a set of four Openspace sims, do they all reside on the *same* CPU as each other?

B) If one Openspace sim crashes (or if you restart it yourself), do the other three on that same CPU crash/restart as well?

Which leads to C) If they do all come on the same CPU/server, will they always stay on the same CPU/server as each other?

Here is the sort of scenario I am curious about. I get four Openspace sims, and they are put to use. At some point, sim "B" is having performance issues. I find nothing suspicious going on in sim "B". If all four share the same CPU I can easly go to sims A, C and D and find out if there's something amiss on one of the other three. If, however, they are on different CPUs / servers from each other, that means that they're sharing server space with somebody else's Openspace sims, which means performance on my Openspace sims is not entirely in my control.

Likewise, if I find something is borked on my Openspace sim B and I restart it, I'm curious / concerned if that will force the other three Openspace sims to restart as well.

Thanks in advance!

A) no, they share with other openspace sims, randomly, must like regular sims do.
B) No, They are independent of each other.
C) again no, see A).

And yes I know this from firsthand knowledge, I do own openspace sims.

A) When you get a set of four Openspace sims, do they all reside on the *same* CPU as each other?
I used to think yes, but I believe the answer is no.

B) If one Openspace sim crashes (or if you restart it yourself), do the other three on that same CPU crash/restart as well?
Absolutely positive this answer is no. I've restarted one of a batch of 4 while standing and watching from another in that batch for it to come back up. You can safely restart one of the 4 and it has no effect on the other 3.

Which leads to C) If they do all come on the same CPU/server, will they always stay on the same CPU/server as each other?
See #1 - I don't think they do.

Thank you both for the replies!
