As mentioned, the current standing issue is a DDoS attack. This does not affect the game servers but the network providers in-between. So it looks like a disconnection. This is why there is a penalty but a starting penalty is small at only a 10 minute suspension.
This tells me you disconnected in three separate competitive games. When you have the first disconnection, try to make every effort to reconnect and complete that game (I know this is not always possible). However, after a first disconnection, make every effort to avoid Competitive Play and investigate to see why you may have disconnected. Attempting to immediately re-queue for Competitive Play without investigating or troubleshooting really is just as bad as deliberately leaving Competitive Games.
