So if your journal's not available now, that's why. Shouldn't be long before it's back up.
BTW, the Green cluster is one of the few remaining cluster that doesn't have two equal halves ("master-master"). Instead it has one "master" and one weaker, read-only "slave". Hence the downtime.. the master's down now.
We have two new database machines in our possession but not fully setup and two more to be delivered shortly which will let us ditch all our old master-slave setups and move entirely to master-master.
Anyway, sorry about this. Lisa or I will post an update in a bit.
