Re: edit, yep I believe it is full mesh sync for homeservers in a room, but if for some reason two can't communicate they can get the graph from other servers.

Re: edit, yep I believe it is full mesh sync for homeservers in a room, but if for some reason two can't communicate they can get the graph from other servers. It's eventually consistent if the homeservers are connected through any path, but it tries to be full-mesh. Scalability I think will be tackled to make P2P more practical, though. Sorry you had that issue!
