Yeah.... Doxing is pretty much pure evil. There's no excuse for that, it's like putting a hit out on someone.
I'd like to further clarify that Microsoft and Sony are at (or should be at, if they aren't) the *highest* tier of bandwidth available. If a DDoS is able to take it down, it is purely because they have a crappy infrastructure. We deal with medium DoS attacks regularly at my company, and they really don't effect the whole network until they're enormous. If we had the resources available to Sony and Microsoft, it wouldn't be an issue.
I'd like to reinforce this idea by mentioning that these same people pulled the same kind of attack on Steam yesterday. It's been reported that 1 server kinda went "hrrrnghh" for about 15 minutes before its firewall caught up and it was fine too.
I'd also like to rebut the "LA fired Google" thing... I don't *care* if one giant corporation fired another giant corporation. This was about a small group of 10 or 15 people causing major grief for a couple of giant corporations with *NO* effort. This is equivalent to people putting a cow on the roof of the high school. It shows the administration that there are real problems that need solutions, and that their security is lax and complacent. We need things like this to happen from time to time, or something legitimately bad is going to end up happening.
tl;dr
