Does unintentionally disconnecting count as a loss?

My internet shut off during a comp game with my friends. When I was able to restore it, it was too late. I was on a four game win streak; does this count as a loss?

Solution 1:

Not only does it count as a loss, you also get a ban for disconnecting while playing Competitive somewhere between 30 Minutes and 7 Days, unless you are able to reconnect to the game within 5 minutes. The length of the ban depends on your previous record and will get longer over time.

I can only recommend not to play Competitive if your internet connection is not stable enough to hold one full game of a maximum amount of 90-100 minutes.

There is no way the game can tell if a disconnect is intentional or not, so there are measures in place to punish notorious leavers.
