iMessage suddenly offline
Haven't changed anything. Today my accounts are offline. Attempt to sign in again with Apple ID, and received the message that the server is not responding and to try later. Well, my partner has no problem with it so it can't be the server. Tried restarting. Any idea what I can do about this? It's never happened before.
