I am deploying to production which is the sole load-balanced environment. I have an issue with regard to a Delayed-Published page in this environment. If I subscribe to this event, do all nodes in the pool recieve this event? Or does only one?
Only the instance that does the actual publishing get's this event. All other instances will get a notification to remove the page from the cache to be able to reload it's data from the database. If all instances would get the event, you would have a much more complex logic if you for instance want to synchronize something with another system since there will be lots of simultaneous events.
