Yeah, I was logged in about 10-15mins before as well, and no issues here. It's always best to get logged in to streaming early before you get the rush of everyone signing in at the last minute and overloading the system.
Blackouts still happen. In a 82 game season, there are 26 games that are not shown on Sportsnet here. The other 56 Toronto games get shown (16 regional + 40 national). And if you live outside of the region for each team - you only get to see their games that are classes as national game.
