Reduce risk that critical (communication) services are down at the same time

Yesterday we had short outages of chives which a bunch of us use for IRC. I said "Okay, fine, let's do email in the mean time" until I realized that our shiny new submission service was affected by the same outage. We should think about critical (communication) services trying to make sure they are on different networks, so we reduce the risk that all/most of them are down at the same time.
