WEIRD Disconnet

So I just had a game and suddenly I lost connection, and after it didnt reconnect for 1 minute i checked my internet which was fine. I then proceeded to restart my client, but instead of letting me get back into the game I am back in the lobby, and I could re-queue for another game, and the history didnt show that game either. I added my previous teammates and even enemies from that match, and it seems that it happened to everyone. Is this a system error? cause I've never had this happen before.
