Reminder: Matrix is "up". The "matrix.org" homeserver is "down" today (https://status.matrix.org), but that doesn't stop matrix from working. Your matrix rooms are still "up", even those with "matrix.org" addresses.
What does that mean? User accounts registered on "matrix.org" (ending in ":matrix.org") are offline today. Everybody else is still there in your rooms, chatting away.
How is that? That's because a matrix chat room exists jointly and independently across the servers of all its members. A room is not "on" a server. When any server goes down, all the room members registered on other servers can continue chatting among themselves. No matter if the server that created the room goes down. Even if the server named in the room's address or "alias" goes down.
A prominent Matrix server is down today, affecting the users registered on it. But the rooms are not down, for everyone registered on other servers, because a room is not "on" a server. Matrix stays up.
