@claus It's saved on both servers, and updated on both servers if the commenter edits it.I guess at a technical level it is being delivered from the server where the interface is based, so if you were viewing from server B's website it would be delivered from B.This means if server A goes down temporarily, its posts will still be visible when viewed from server B. (At some point though posts may disappear if a remote server stops responding or if it sends out a delete request.)
