I actually don't think it's a big deal that there were technical problems, there were millions of people trying to get in at the same time. What I don't like is him lying that it was a ddos attack.
What's weird to me though, is if they were just overloaded at the time, wouldn't it make a lot more sense to just say that and sound like you're super popular and in demand, than to make up some fake attack? I guess persecution complex beats ego stroking.
