Aside from their biggest feature, which is getting people to consistently show up in instances not working as intended for days, yeah perfectly.I think Destiny's alpha and beta ran almost perfectly.
Bungie also kind of fathered modern matchmaking in video games and has previously handled record breaking first day online numbers game after game after game, so it's pretty different. Not sure why this is a point of comparison vs. Capcom developing new tech and testing it out for a different service than they've ever had before.
