Dota2 is Valve's first multiplayer game where they run all the servers themselves. It's also their most popular game (by a factor of 10x) [0]. Scaling to that number of players takes a lot of work, and from what I've seen (comments from Valve devs), their devops team is only 2 people [1]. The current server instability has to do with a large patch (550MB) sent out yesterday that added a new game mode that is actually an addon[2]. This addon system looks fairly new and may be taking its toll on the servers.
