People dropping out at the load screen

It seems like in the last few days, most of the Pantheon games I try to play break after the connection is initially established, while the level is being loaded.  The symptom is that the load screen just sits there for a much longer period than normal.  After a while, I hear "a player has left the game".  Sometimes the load screen sits there for another fifteen to thirty seconds before the game starts; other times, I'm stuck for several minutes longer before I hear "a player has left the game" again and the game starts immediately, with no human players.

Is there anything I can change on my end to reduce the frequency of these drops?
