On Android, brief internet connection loss results in "waiting for server..." Message and removal from the current game upon reconnection (placed back in lobby).
Closing the game and relaunching puts you back in the game, but this is impossible to do quickly enough if there are no timer expansions (you will loose at least 1 turn)
This happened to me twice during a quick draft today, but it is a recurrent issue in all games.
The reconnect is infuriating because it seems like it could be much faster (shows player names, goes through a queue like wait, etc.).
