Shouldn't be surprised it's not working properly, but that doesn't mean it's acceptable. Too many people think it's ok when things don't work these days because 'it's only just launched'.
Well, I agree that it sucks. However, its just one of those logistical things that can't be solved short of tossing astronomical amounts of money at it; an amount that is largely wasted after the "new thing rush" is over and you're not worried about millions of people slamming your servers all at once.
